[0074] The definitions of each substituent in the aforementioned general formula I also apply to I'.

[0085] Table 5
[0086] The compound of formula (I) of the present invention may exist in the form of one or more stereoisomers. Stereoisomers are isomers with the same composition but different atomic spatial arrangements, including enantiomers, diastereomers, cis-trans isomers (also called geometric isomers), and trans-isomers. Trans-isomers arise from restricted rotation around a single bond, where the rotational energy barrier is high enough to allow the separation of isomeric substances. Those skilled in the art will understand that when a stereoisomer is enriched relative to other stereoisomers, or when it is separated from other stereoisomers, it may be more active and / or may exhibit beneficial effects. Furthermore, those skilled in the art know how to separate, enrich, and / or selectively prepare said stereoisomers.
[0087] "Stereoisomer" or "stereoisomeric form" refers to a stereoisomer of a compound that is substantially free of other stereoisomers of the compound. For example, a stereoisomerically pure compound having one chiral center will substantially be free of its opposite enantiomers. A stereoisomerically pure compound having two chiral centers will substantially be free of its other diastereomers. A typical stereoisomerically pure compound contains more than about 60% by weight of one stereoisomer and less than about 40% by weight of other stereoisomers of the compound, more than about 80% by weight of one stereoisomer and less than about 20% by weight of other stereoisomers of the compound, more than about 90% by weight of one stereoisomer and less than about 10% by weight of other stereoisomers of the compound, more than about 95% by weight of one stereoisomer and less than about 5% by weight of other stereoisomers of the compound, or more than about 97% by weight of one stereoisomer and less than about 3% by weight of other stereoisomers of the compound. The compounds may have a chiral center and may exist as racemic, enantiomers alone, or diastereomers and mixtures thereof. All such isomeric forms (including mixtures thereof) are included in the examples disclosed herein. The use of the stereoisomeric pure forms of such compounds and the use of mixtures of those forms are included in the examples disclosed herein. For example, mixtures comprising equal or unequal amounts of enantiomers of a particular compound may be used in the methods and compositions disclosed herein. These isomers may be asymmetrically synthesized or resolved using standard techniques such as chiral columns or chiral resolving agents.
[0088] The compounds of formula (I) of the present invention generally exist in more than one form, and therefore all crystalline and amorphous forms of the compounds of formula (I). Amorphous forms include embodiments as solids, such as waxes and gums, and embodiments as liquids, such as solutions and melts. Crystalline forms include embodiments that substantially represent a single crystal type and embodiments that represent mixtures of polymorphs (i.e., different crystal types). The term "polymorph" refers to a specific crystalline form of a compound that can crystallize in different crystalline forms, having different arrangements and / or conformations of molecules in the crystal lattice. Although polymorphs may have the same chemical composition, their compositions may also differ due to the presence or absence of co-crystallization water or other molecules that can be weakly or strongly bound in the crystal lattice. The chemical, physical, and biological properties of polymorphs may differ, such as crystal shape, density, hardness, color, chemical stability, melting point, hygroscopicity, suspension, dissolution rate, and bioavailability. Those skilled in the art will understand that, relative to another polymorph or mixture of polymorphs of the same compound represented by formula (I), a polymorph of the compound represented by formula (I) may exhibit beneficial effects (e.g., suitability for preparing useful formulations, improved biological properties). The preparation and isolation of specific polymorphs of the compound represented by formula (I) can be achieved by methods known to those skilled in the art, including, for example, crystallization using selected solvents and temperatures. The compounds of the present invention can exist as one or more crystalline polymorphs. The present invention includes individual polymorphs and mixtures of polymorphs, including mixtures enriched in one polymorph relative to other polymorphs.
[0089] The present invention also provides a method for preparing the compound of formula (I) described above, its N-oxide, its stereoisomers, and its agriculturally acceptable salts.

At least one of formamide, N,N-dimethylacetamide, or dimethyl sulfoxide; the base is selected from at least one of 4-dimethylaminopyridine (DMAP), trimethylamine, triethylamine, diisopropylethylamine, pyridine, 2-methylpyridine, 3-methylpyridine, 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), or 2,6-dimethylpyridine; the dehydrating coupling agent is selected from propylphosphonic anhydride, butylphosphonic anhydride, dicyclohexylcarbodiimide, N-(3-dimethylaminopropyl)-N'ethylcarbodiimide, N,N'-carbonyldiimidazole, 2-chloro-1,3-dimethylimidazolium chloride, or 2-chloro-1-methylpyridinium iodide. Polymer-supported agents, such as polymer-supported cyclohexylcarbodiimide, are also suitable. These reactions are typically carried out at temperatures ranging from 0°C to 60°C; for coupling conditions using butylphosphonic anhydride, see Organic Process Research & Development, 2009, 13, 900-906; R1, R2, R3 and J are as defined above.
[0091] This invention also provides another method for preparing the compound of formula (I) described above, its N-oxide, its stereoisomers, and its agriculturally acceptable salts.
[0092] J-NH2 reacts with a compound of formula (II-A) in an organic solvent in the presence of a base to prepare a compound of formula (I), wherein the organic solvent is selected from pentane, n-hexane, cyclohexane, heptane, octane, dichloromethane, 1,2-dichloroethane, chloroform, carbon tetrachloride, petroleum ether, diethyl ether, methyl tert-butyl ether, ethylene glycol dimethyl ether, tetrahydrofuran, 2-methyltetrahydrofuran, 1,4-dioxane, ethyl acetate, butyl acetate, benzene, toluene, o-xylene, m-xylene, p-xylene, xylene, chlorobenzene, acetone, butane, etc. The base is selected from at least one of the following: ketone, 4-methyl-2-pentanone, cyclohexanone, N-methylpyrrolidone, acetonitrile, N,N-dimethylformamide, N,N-dimethylacetamide, or dimethyl sulfoxide; the base is selected from at least one of 4-dimethylaminopyridine (DMAP), trimethylamine, triethylamine, diisopropylethylamine, pyridine, 2-methylpyridine, 3-methylpyridine, 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), or 2,6-dimethylpyridine; R1, R2, R3, and J are as defined above.
[0093] Specifically, the compounds of formula (II-A) of the present invention can be prepared by the various methods listed below:
[0094] Option 1:
[0095] As shown in Scheme 1, acyl chlorides having formula (II-A) can be readily prepared from carboxylic acids having formula (II) by many well-known methods. For example, reacting the carboxylic acid in a solvent such as dichloromethane or toluene, and optionally in the presence of a catalytic amount of N,N-dimethylformamide, with a chlorinating agent (such as thionyl chloride, oxalyl chloride, or phosphorus oxychloride) can provide the corresponding acyl chloride having formula (II-A).
[0096] Option 2:
[0097] As shown in Scheme 2, carboxylic acids having formula (II) can be prepared, preferably in a slightly excess of a base hydroxide (e.g., lithium hydroxide), at a temperature between about 0°C and 45°C, by a well-known method of basic or acidic hydrolysis of the corresponding compound having formula (III), in an aqueous cosolvent such as methanol, ethanol, or tetrahydrofuran. The product can be separated by acidification, followed by filtration or extraction (optionally after removal of the organic solvent by evaporation). Ak represents a lower alkane, such as methyl or ethyl.
[0098] Option 3:
[0099] As outlined in Scheme 3, esters having formula (III) can also be prepared from ketones having formula (V) via a two-step procedure. In the first step, the ketone having formula (V) is condensed with a trifluoromethyl ketone having formula (VI) to provide a compound having formula (IV). This reaction is typically carried out in the presence of a base such as calcium hydroxide, potassium carbonate, or cesium carbonate, in a solvent or mixture of solvents such as toluene, N,N-dimethylformamide, 2-methoxy-2-methylpropane (MTBE), (trifluoromethyl)benzene, 1,2-dichloroethane, or acetonitrile. Ak represents a lower alkane, such as methyl or ethyl.
[0100] In the second step, the condensation product having formula (IV) is treated with a hydroxylamine or a hydroxylamine salt to produce an isoxazoline compound having formula (III). This reaction is typically carried out under basic conditions. Typical bases include sodium hydroxide, lithium hydroxide, or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU). The reaction can be carried out in solvents or mixtures of solvents such as toluene, N,N-dimethylformamide, 2-methoxy-2-methylpropane (MTBE), (trifluoromethyl)benzene, 1,2-dichloroethane, or acetonitrile. The general procedure for the method of Scheme 3 is described in detail in the chemical literature, see, for example, WO2009126668A.
[0101] Option 4:
[0102] As outlined in Scheme 4, esters having formula (V) can also be prepared from pyridine halides having formula (VIII) via a two-step procedure. In the first step, the halide of formula (VIII) is converted to an organomaglenite in the presence of a Grignard reagent, which is then reacted with acetamide to give an acetyl-functionalized ketone of formula (VII). The Grignard reagent is selected from isopropyl magnesium chloride, isopropyl magnesium chloride-lithium chloride complex, cyclohexyl magnesium chloride, or n-butyl magnesium chloride. The acylating agent is selected from N,N-dimethylacetamide, N-methyl-N-methoxyacetamide, acetyl chloride, acetic anhydride, N-methyl-N-methoxy-2-chloroacetamide, or N-methyl-N-methoxy-2-bromoacetamide. The reaction solvent is tetrahydrofuran, toluene, 2-methyltetrahydrofuran, or dichloromethane. The reaction temperature is generally between -75 and 80 °C.
[0103] In the second step, the ketone having formula (VII) is reacted in the presence of a palladium catalyst under a CO atmosphere to produce an ester compound having formula (V). The palladium catalyst used in the method of the present invention typically comprises palladium in the form of an oxidation state of 0 (i.e., Pd(0)) or 2 (i.e., Pd(II)). A variety of such palladium-containing compounds and complexes can be used as catalysts in the method of the present invention. The palladium catalysts include PdCl2(PPh3)2 (i.e., bis(triphenylphosphine)palladium(II)), Pd2(dba)3 (i.e., tris(dibenzylacetone)palladium(0)), Pd(PPh3)4 (i.e., tetra(triphenylphosphine)palladium(0)), Pd(C5H7O2)2 (i.e., palladium(II) acetylacetone), dichloro-[1,1'-bis(diphenylphosphine)ferrocene]palladium(II), and complexes of palladium acetate with 1,1'-bis(diphenylphosphine)ferrocene. The reaction is typically carried out under alkaline conditions. Typical bases include sodium hydroxide, lithium hydroxide, or 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU), triethylamine, and isopropylethylamine. The reaction can be carried out in solvents or mixtures of solvents such as methanol, ethanol, isopropanol, and n-butanol. Ak represents a lower alkane, such as methyl, ethyl, isopropyl, or n-butyl.

The term "alkylcycloalkyl" indicates alkyl substitution on the cycloalkyl moiety and includes, for example, ethylcyclopropyl, isopropylcyclobutyl, 3-methylcyclopentyl, and 4-methylcyclohexyl. The term "cycloalkylalkyl" indicates cycloalkyl substitution on the alkyl moiety. Examples of "cycloalkylalkyl" include cyclopropylmethyl, cyclopentylethyl, and other cycloalkyl moiety bonded to straight-chain or branched alkyl groups.
[0109] Halogen-substituted alkyl groups (halogenated alkyl groups) refer to the following straight-chain or branched alkyl groups in which some or all of the hydrogen atoms are replaced by halogen atoms, such as C1-C2 haloalkyl groups, including chloromethyl, bromomethyl, dichloromethyl, trichloromethyl, fluoromethyl, difluoromethyl, trifluoromethyl, chlorofluoromethyl, dichlorofluoromethyl, chlorodifluoromethyl, 1-chloroethyl, 1-bromoethyl, 1-fluoroethyl, 2-fluoroethyl, 2,2-difluoroethyl, 2,2,2-trifluoroethyl, 2-chloro-2-fluoroethyl, 2-chloro-2,2-difluoroethyl, 2,2,2-dichloro-2-fluoroethyl, 2,2,2-trichloroethyl, pentafluoroethyl, and 1,1,1-trifluoropropyl-2-yl.

[0110] The term "halogen" refers to fluorine, chlorine, bromine, or iodine. If the term is used with a group, then "halogen" or "halogen atom" refers to a fluorine, chlorine, bromine, or iodine atom.
[0111] As used in this article, the chemical abbreviations S(O) and S(=O) represent the sulfinyl group. The chemical abbreviations SO2, S(O)2, and S(=O)2 represent the sulfonyl group. The chemical abbreviations C(O) and C(=O) represent the carbonyl group. The chemical abbreviations CO2, C(O)O, and C(=O)O represent the oxycarbonyl group. "CHO" means acyl group.
[0112] The terms "carbocyclic ring," "carbocycle," or "carbocyclic system" indicate a ring or ring system in which the atoms forming the ring skeleton are selected only from carbon. The terms "heterocyclic ring," "heterocycle," or "heterocyclic system" indicate a ring or ring system in which at least one atom forming the ring skeleton is not carbon (e.g., nitrogen, oxygen, or sulfur). Typically, a heterocyclic ring contains no more than four nitrogen atoms, no more than two oxygen atoms, and no more than two sulfur atoms. Unless otherwise specified, a carbon ring or heterocyclic ring can be saturated or unsaturated. "Saturated" means a ring having a skeleton consisting of atoms connected to each other by single bonds; unless otherwise specified, the remaining atoms are occupied by hydrogen atoms. Unless otherwise stated, an "unsaturated ring" can be partially unsaturated or completely unsaturated. The term "fully unsaturated ring" refers to a ring of atoms in which the bonds between atoms are either single or double bonds according to valence bond theory, and furthermore, the bonds between atoms in the ring include as many double bonds as possible, but no cumulative double bonds (i.e., no C=C=C or C=C=N). The term "partially unsaturated ring" indicates a ring containing at least one ring member bonded to a neighboring ring member by a double bond, and conceptually may accommodate more than the number of non-cumulative double bonds (i.e., their fully unsaturated counterparts) between adjacent ring members.
[0113] Unless otherwise specified, heterocyclic and cyclic systems can be attached by any available carbon or nitrogen in place of hydrogen on said carbon or nitrogen.
[0114] The term "aromatic" indicates that each ring atom of a fully unsaturated ring is substantially in the same plane and has p-orbitals perpendicular to the ring plane, and that (4n+2) π electrons (where n is a positive integer) are associated with the ring to conform to Hückel's rule.
[0115] The term "aromatic ring system" refers to a ring system in which at least one ring is an aromatic carbon ring or heterocyclic system. When the fully unsaturated carbon ring satisfies Hückel's rule, the ring is also called an "aromatic ring" or "aromatic carbon ring." The term "aromatic carbon ring system" refers to a ring system in which at least one ring is an aromatic carbon ring. When the fully unsaturated heterocyclic ring satisfies Hückel's rule, the ring is also called a "heteroaromatic ring" or "aromatic heterocyclic ring." The term "aromatic heterocyclic system" refers to a ring system in which at least one ring is an aromatic heterocyclic system.
[0116] The term "non-aromatic ring system" refers to a carbon ring or heterocyclic system that can be fully saturated, partially or fully unsaturated, provided that none of the rings in the system are aromatic. The term "non-aromatic carbon ring system" refers to a system in which no ring is an aromatic carbon ring. The term "non-aromatic heterocyclic system" refers to a heterocyclic system in which no ring is an aromatic ring.
[0117] The term "optionally substituted" in relation to heterocycles refers to a group that is unsubstituted or has at least one non-hydrogen substituent that does not eliminate the biological activity possessed by the unsubstituted analogue. As used herein, unless otherwise specified, the following definitions shall apply. The term "optionally substituted" is used interchangeably with the phrase "substituted or unsubstituted" or the term "(un)substituted." Unless otherwise specified, an optionally substituted group may have substituents at each substituted position of the group, and each substitution is independent of the others.

[0119] The compounds of the present invention can exist as mixtures of stereoisomers or as individual stereoisomers. For example, two possible enantiomers having formula (I) are described as formula I' and II' involving the isoxazoline chiral center identified by an asterisk (*). Similarly, other chiral centers may exist, for example, at J.
[0120] The molecular descriptions in this paper follow standard conventions for depicting stereochemistry. To indicate stereochemistry, bonds extending from the drawing plane toward the viewer are represented by solid wedges, with the wide end of the wedge connected to an atom extending from the drawing plane toward the viewer. Bonds extending below the drawing plane and away from the viewer are represented by dashed wedges, with the wide end of the wedge connected to an atom further away from the viewer.
[0121] Since chiral carbon atoms may be present in formula (I), the invented compound can exist as stereoisomers. Therefore, the invented compound includes individual stereoisomers of the compound having formula (I), as well as mixtures of stereoisomers of the compound having formula (I).
[0122] The present invention includes racemic mixtures, such as equal amounts of enantiomers having formula I' and I". Furthermore, the invention includes compounds enriched compared to racemic mixtures of enantiomers having formula (I). It also includes substantially pure enantiomers of compounds having formula (I) (e.g., formulas I' and I").
[0123] When enantiomers are enriched, one enantiomer is present in a larger amount than the other, and the degree of enrichment can be defined as an enantiomer excess of (2x-1)·100% (“ee”), where x is the mole fraction of the dominant enantiomer in the mixture (e.g., 20% ee corresponds to a 60:40 ratio of enantiomers). Preferably, the invented composition has an enantiomer excess of at least 50% of the more active isomer; more preferably at least 75%; even more preferably at least 90%; and most preferably at least 94%. Particularly noteworthy are examples of enantiomer purity of the more active isomer.
[0124] Compounds having formula (I) may contain additional chiral centers. For example, substituents and other molecular components such as J itself may contain chiral centers. The invention includes racemic mixtures and substantially pure stereoconfigurations enriched at these additional chiral centers.
[0125] The invented compounds can exist as one or more conformational isomers due to rotational restriction around the amide bond (e.g., C(=O)-N) in formula (I). The invention includes mixtures of conformational isomers. Furthermore, the invention includes compounds in which one conformational isomer is enriched relative to other conformational isomers.
[0126] The invention includes all stereoisomers, conformational isomers and mixtures thereof in all proportions, as well as isotopic forms such as deuterated compounds.
[0127] Those skilled in the art will understand that not all nitrogen-containing heterocycles can form N-oxides, because nitrogen requires a lone pair of electrons to be oxidized into an oxide; those skilled in the art will recognize which nitrogen-containing heterocycles can form N-oxides. Those skilled in the art will also recognize that tertiary amines can form N-oxides. Synthetic methods for preparing N-oxides of heterocycles and tertiary amines are well known to those skilled in the art, including the oxidation of heterocycles and tertiary amines using peroxyacids such as peracetic acid and 3-chloroperoxybenzoic acid (MCPBA), hydrogen peroxide, alkyl hydroperoxides such as tert-butyl hydroperoxide, sodium perborate, and diethylene oxides such as dimethyldiethylene oxide. These methods for preparing N-oxides have been extensively described and reviewed in the literature.
[0128] Based on the properties of the substituents defined above, compounds of formula (I) are acidic and can form salts, and, if suitable, can form internal salts, or form adducts with inorganic or organic bases or with metal ions. If compounds of formula (I) contain a hydroxyl group, a carboxyl group, or other groups that cause acidity, these compounds can react with bases to form salts. Suitable bases are, for example, hydroxides, carbonates, and bicarbonates of alkali metals and alkaline earth metals, particularly sodium, potassium, magnesium, and calcium; and ammonia; primary, secondary, and tertiary amines having C1-C4-alkyl groups; monoalkylolamines, dialkylolamines, and trialkylolamines of C1-C4-alkanols; choline and choline chloride; and organic amines such as trialkylamines, morpholine, piperidine, or pyridine. These salts are compounds in which the acidic hydrogen is replaced by an agriculturally suitable cation, for example, metal salts, especially alkali metal salts or alkaline earth metal salts, particularly sodium and potassium salts; or ammonium salts, organic amine salts, or quaternary ammonium salts, such as salts of cations having the formula [NRR′R″R″′]+ (where R to R″′ each independently represents an organic group, particularly alkyl, aryl, aralkyl, or alkylaryl). Also suitable are alkyl sulfonium salts and alkyl oxide sulfonium salts, such as C1-C4-trialkyl sulfonium salts and C1-C4-trialkyl oxide sulfonium salts.
[0129] Compounds of formula (I) can form salts by adding a suitable inorganic or organic acid to a basic group; the inorganic acid being, for example, HCl, HBr, H₂SO₄, H₃PO₄, or HNO₃, the organic acid being, for example, a carboxylic acid (e.g., formic acid, acetic acid, propionic acid, oxalic acid, lactic acid, or salicylic acid) or a sulfonic acid (e.g., p-toluenesulfonic acid), and the basic group being, for example, an amino, alkylamino, dialkylamino, piperidinyl, morpholinyl, or pyridinyl group. In this case, the salts contain the conjugate base of the acid as an anion.

[0185] At 0 °C under a nitrogen atmosphere, 1.3 M isopropyl magnesium chloride-lithium chloride complex (242 mL, 315 mmol) was added dropwise to 2-chloro-3-methyl-5-bromopyridine (50.0 g, 242 mmol) in tetrahydrofuran (100 mL) over 30 minutes. After 90 minutes, N-methoxy-N-methylacetamide (32.4 g, 314.6 mmol) was added dropwise. The reaction mixture was stirred at room temperature for 12 hours. After the reaction was complete, it was quenched by adding 20 mL of saturated ammonium chloride aqueous solution. The reaction mixture was extracted with ethyl acetate (3 x 100 mL). The combined organic layers were washed with water, dried over sodium sulfate, and concentrated under reduced pressure to give 39.0 g of yellow solid. LCMS (ESI): m / z 170 [M+H] + .

The resulting reaction mixture was cooled to -20 °C, and 10 M potassium carbonate solution (16.2 mL, 161 mmol) was added. The reaction mixture was stirred at this temperature for 30 minutes, followed by slow dropwise addition of hydroxylamine solution (50% in H2O, 8.92 mL, 147 mmol). The mixture was stirred at this temperature for 2 days. After the reaction was complete, the mixture was brought to room temperature, diluted with water, and extracted with dichloromethane (3 x 50 mL).
