DETAILED DESCRIPTION The method of this disclosure is generally applicable to a wide range of compounds of Formula 1, 2 and 3. In the recitations herein, although the R1, R2, R3and R4substituents are connected to the backbone of the phenyl ring, the R1, R2, R3and R4substituents are separated from the reaction center. The R1, R2, R3and R4substituents can encompass a variety of groups preparable by modern methods of organic chemistry. One skilled in the art will recognize that certain groups are to the reagents of this method and may be transformed under the reaction conditions. As used herein, the terms “comprises,” “comprising,” “includes,” “including,” “has,” “having,” “contains”, “containing,” “characterized by” or any other variation thereof, are intended to cover a non-exclusive inclusion, subject to any limitation explicitly indicated. For example, a composition, mixture, process or method that comprises a list of elements is not necessarily limited to only those elements but may include other elements not expressly listed or inherent to such composition, mixture, process or method. The transitional phrase “consisting of” excludes any element, step, or ingredient not specified. If in the claim, such phrase would close the claim to the inclusion of materials other than those expressly recited except for impurities ordinarily associated therewith. When the phrase “consisting of” appears in a clause of the body of a claim, rather than immediately following the preamble, it limits only the element set forth in that clause; other elements are not excluded from the claim as a whole. The transitional phrase “consisting essentially of” is used to define a composition, process or method that includes materials, steps, features, components, or elements, in addition to those literally disclosed, provided that these additional materials, steps, features, components, or elements do not materially affect the basic and novel characteristic(s) of the disclosure. The term “consisting essentially of” occupies a middle ground between “comprising” and “consisting of”. Where applicants have defined an embodiment or a portion thereof with an open-ended term such as “comprising,” it should be readily understood that (unless otherwise stated) the description should be interpreted to also describe such an embodiment using the terms “consisting essentially of” or “consisting of.” Further, unless expressly stated to the contrary, “or” refers to an inclusive or and not to an exclusive or. For example, a condition A or B is satisfied by any one of the following: A is true (or present) and B is false (or not present), A is false (or not present) and B is true (or present), and both A and B are true (or present). Also, the indefinite articles “a” and “an” preceding an element or component of the disclosure are intended to be nonrestrictive regarding the number of instances (i.e., occurrences) of the element or component. Therefore “a” or “an” should be read to include one or at least one, and the singular word form of the element or component also includes the plural unless the number is obviously meant to be singular. As used herein, the term "alkyl", used either alone or in compound words such as "haloalkyl," "alkylcycloalkyl," "cycloalkylalkyl" or "alkylcycloalkylalkyl," includes straight-chain or branched alkyl groups having one to four carbon atoms, e.g., methyl, ethyl, n-propyl, i-propyl, or the different butyl isomers.

Examples of “alkylcycloalkylalkyl” include methylcyclohexylmethyl and ethylcycloproylmethyl. The term “cyclopropylcyclopropyl,” denotes cyclopropyl substitution on another cyclopropyl ring. Examples of “cyclopropylcyclopropyl,” include 1,1'- bicyclopropyl-1-yl, 1,1'-bicyclopropyl-2-yl and the different cis- and trans- cyclopropylcyclopropyl isomers such as (1R,2S)-1,1'-bicyclopropyl-2-yl and (1R,2R)-1,1'- bicyclopropyl-2-yl. The term “dialkylaminoalkyl” denotes two independent straight-chain or branched alkyl moieties bonded to a nitrogen atom of an amino(straight-chain or branched)alkyl moiety. Examples of “dialkylaminoalkyl” include (CH3)2NCH2-, (CH3)2CH(CH3)NCH2- and (CH3)2NCH(CH3)-. The term “halogen”, either alone or in compound words such as “haloalkyl” or “haloalkoxy”, includes fluorine, chlorine, bromine or iodine. Furthermore, when used in compound words such as “haloalkyl”, said alkyl may be partially or fully substituted with halogen atoms which may be the same or different.

In addition, embodiments of this disclosure, including Embodiments 1-C33 above as well as any other embodiments described herein, and any combination thereof, pertain to the methods of the present disclosure. In the following Schemes the definitions of R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, X and L in the compounds of Formula 1 through 7 below are as defined above in the Summary unless otherwise indicated. As shown in Scheme 1, this disclosure relates to a method for preparing a compound of Formula 1 catalyzed carbonylation, followed by amination. In the present method an of Formula 3 and an alcohol of Formula 4 are combined (i.e., contacted) in the presence of a palladium source, a ligand, a base and carbon monoxide to provide the corresponding aminobenzoate ester of Formula 2, which is then treated with an amine of Formula 5 to provide the corresponding aminobenzamide of Formula 1. Scheme 1 The palladium source can be either a soluble palladium compound or palladium source on an insoluble support. Examples of suitable soluble palladium compounds include palladium(II) carboxylates, such as palladium(II) acetate (i.e., Pd(OAc)2), palladium(II) trifluoroacetate, palladium(II) propionate, and palladium(II) benzoate; palladium salts of mineral acids, such as palladium(II) chloride (i.e., PdCl2), palladium(II) bromide, and palladium(II) sulfate; and other palladium complexes such as (dibenzylideneacetone)dipalladium(0) and palladium(II) acetylacetonate (i.e., Pd(acac)2), all of which are commercially available. Examples of suitable supported palladium sources include palladium on carbon and palladium (II) hydroxide on carbon. Numerous grades of unreduced and pre-reduced palladium on carbon are commercially available containing from 1 to 20 wt% palladium with different metal deposition patterns (e.g., uniform and eggshell), and utilize a variety of carbon types (e.g., peat, coconut and wood). The ligand of the present disclosure can be a bidentate phosphine such as the compound of Formula 7 as shown below in Figure 1. Figure 1 In the compound of Formula 7, L is a substituted or unsubstituted bridging group. Examples of suitable L groups include, but are not limited to, -(CH2)n-, 1,4'-ferrocene, 2,2'-diphenyl ether, 1,2-xylene and 4,5-xanthene. In a compound of Formula 7, each R7, R8, R9and R10is independently aryl or aryl. Examples of aryl groups used herein include monocyclic aromatic hydrocarbons as phenyl) and oxygen-containing aromatic heterocycles (such as furyl). Examples of substituted aryl groups as used herein include aryl groups where one or more hydrogens of the aryl group have been replaced by an alkyl, alkoxy, chlorine, fluorine or fluoromethyl group (e.g. tolyl, and xylyl). Ligands of particular note in the present disclosure include 1,4-bis(diphenylphosphino)butane (dppb), 1,1'-bis(diphenylphosphino)ferrocene (dppf), and 9,9-dimethyl-4,5-bis(diphenylphosphino)- xanthene (Xantphos). In the context of the present disclosure the palladium source is most often combined with the ligand (i.e., compound of Formula 7) at the start of the carbonylation reaction. The palladium source and ligand, however, may also be provided in the form of a pre-formed complex (i.e., of palladium source and ligand). Examples of pre-formed complexes useful in the present disclosure include the commercially available [1,1’-bis(diphenylphosphino)- ferrocene]palladium(II) dichloride and (9,9-dimethyl-4,5-bis(diphenylphosphino)xanthene)- palladium(II) dichloride. Catalyst loadings that are less than 0.1 mol% may be achieved with a single use of a soluble palladium source as the catalyst. Typically, with a soluble palladium source, the palladium to ligand molar ratio is from about 1:0.5 to 1:100. A ratio between 1:10 and 1:5 provides the quickest carbon monoxide uptake resulting in reduced reaction times. Use of a soluble palladium source and ligand to form a highly active catalyst system is exemplified by the combination of palladium (II) acetate and the ligand 1,1'-bis(diphenylphosphino)ferrocene (dppf). As demonstrated in Step A of present Examples 1 and 2, and Experiment 10 of Example 3, complete conversion of the starting material may be consistently attained with 0.01 mol% palladium (II) acetate and 0.10 mol% dppf (i.e., a palladium to ligand ratio of 1:10) after a period of 7-8 hours at 120 °C under a carbon monoxide pressure of 75 psig (0.52 MPa). Selectivity for the desired product was 94.7 to 96.7 Area% by HPLC. Alternatively, due to the insolubility of the support material in the reaction mass, catalyst loadings that are less than 0.1 mol% may also be achieved through recycling of a supported palladium source as the catalyst. Typically, with a supported palladium source, the palladium to ligand molar ratio is from about 1:1 to 1:5 in the first run using fresh a supported palladium source and then about 1:0.5 to 1:5 in subsequent runs using the recycled palladium source. Use of a supported palladium source and ligand is exemplified by palladium on carbon (e.g., Johnson Matthey 10R39) combined with the ligand 1,1'-bis(diphenylphosphino)ferrocene (dppf). As demonstrated in Step A of Example 6, complete conversion of the starting material was attained with 0.10 mol% of fresh palladium on carbon and 0.50 mol% dppf (i.e., a palladium to ligand ratio of 1:5) after a period of about 4 hours at 120 °C. The palladium on carbon (i.e., supported palladium source) was recovered from the reaction mass by a combination of decantation and filtration. The recovered material was recycled in Experiment A of Example 7 to which 0.50 mol% dppf added. Under the same reaction conditions, conversion was complete after about 6 A second recycle was carried out in the same manner (see Experiment B of Example 7) resulting in complete conversion after about 7 hours. Selectivity for the desired product ranged from 96.3-97.0 Area% by HPLC. Given that one charge of palladium on carbon was used for all three runs, the effective catalyst loading was 0.033 mol% (i.e., 0.1 mol% divided by 3 runs). The carbonylation reaction of Scheme 1 produces HX (wherein X is Br or I) as a by- product, which is neutralized by addition of a base. In general, any base compatible with the reaction mixture and process conditions may be employed. Organic bases such as tertiary amines (e.g., triethylamine or tributylamine) are particularly suitable. Inorganic bases such as sodium carbonate or sodium bicarbonate; and hydroxides of sodium, calcium, cesium and potassium may also be used. At least 1 molar equivalent of base versus compound of Formula 3 is required by stoichiometry. Reliable high conversions of the compounds of Formula 3 to the compounds of Formula 2 were typically achieved with 1.5 to 3.0 molar equivalents of base relative to the compound of Formula 3. Although higher levels of base can be used there is no particular advantage in doing so and higher levels increase raw material and waste processing costs. The process of Scheme 1 is typically conducted in a suitable organic solvent. Examples of suitable organic solvents include ethers, such as tetrahydrofuran and 2,5,8-trioxanonane (diglyme); nitriles, such as acetonitrile; aromatic hydrocarbons, such as xylenes and toluene; amides, such as N,N-dimethylformamide and N,N-dimethylacetamide; and mixtures thereof. Alcohols of Formula 4 may serve as both the reactant in the carbonylation reaction and the solvent for the process. Examples include alcohols, such as methanol, ethanol and ethylene glycol; and amino-alcohols, such as N,N-dimethylethanolamine; and mixtures thereof. Bifunctional solvents, such as ethylene glycol and N,N-dimethylethanolamine, either alone or in combination, are particularly advantageous in improving the rate and selectivity of the amination reaction. Phosphine ligands are sensitive to the presence of oxygen in the process of Scheme 1. As a result, the process is preferentially carried out under substantially oxygen free conditions to maintain catalyst activity and prevent formation of unwanted by-products. Standard techniques that can be used to remove oxygen include purging the reactor system and / or sparging the starting material solution with an inert gas, such as nitrogen or argon. The presence of water may also lead to degradation of certain phosphine ligands and formation of by-products. Hence, solvents used in the process should be substantially water free. Standard solvent drying techniques that may be used include azeotropic distillation or drying agents such as molecular sieves, potassium carbonate and magnesium sulfate. Process conditions, such as temperature and carbon monoxide pressure, and the catalyst system consisting of a palladium source and a ligand, are selected to achieve high catalyst activity and product selectivity. The activity” in the context of the present disclosure refers to the required catalyst expressed in mol% versus the starting material (i.e., compound of Formula 3), that results in complete or near complete consumption (i.e., 98% or greater) of the starting material in an acceptable period of time (i.e., 18 h or less). The carbonylation reaction is typically conducted between about 70 °C and 150 °C, and preferably between about 100 °C to 120 °C for complete or near complete conversion of the starting material in a commercially acceptable period of time while maintaining a high selectivity. Catalyst loadings that are less than 0.1 mol% are utilized in the present disclosure at carbon monoxide pressures of 70 psig (0.48 MPa) or greater for complete or near complete conversion of the starting material in a commercially acceptable period of time while maintaining a high selectivity. Typically, pressures between about 70 and 225 psig (0.48 to 1.5 MPa) are generally preferred in order to utilize standard, multipurpose, commercial equipment. In the present disclosure, carbon monoxide pressures greater than 70 psig (0.48 MPa) and properly selected catalyst-ligand combinations with low palladium catalyst loadings (i.e., 0.05 mol% or less) result in near to complete conversion of the starting material within 16 h or less. The reaction mass produced from the carbonylation reaction may be used in the subsequent amination stage of the process without the need to isolate the carbonylated product (i.e., the compound of Formula 2). Typically, when a soluble palladium source is used in the carbonylation step of Scheme 1, the entire reaction mass obtained can be used in the subsequent amination reaction. Alternatively, when using a supported palladium source, the supported palladium source is removed from the reaction mass by techniques well known to those skilled in the art, such as decantation or filtration. As discussed above, recovered supported palladium may be recycled to subsequent carbonylation reactions in place of fresh material. Optionally, by-products, such as the base-HX salt formed in the carbonylation reaction, may be removed from the reaction mass by standard techniques well known to those, such as extraction. Furthermore, the carbonylated product may be isolated and purified from the reaction by standard techniques well known to those skilled in the art, such as crystallization and filtration. In the second step of Scheme 1, an amination reaction is typically carried out by contacting the reaction mass containing an ester compound of Formula 2 produced from the carbonylation reaction with an amine of Formula 5. The amine of Formula 5 may be added as a pure material or as a solution in a suitable solvent as previously described for the carbonylation reaction. The solvent may be the same or different from that used for the carbonylation reaction. The amination reaction is typically conducted at temperatures between 70 °C and 150 °C. Temperatures between 80 °C and 120 °C are especially preferred, since they provide complete or near complete consumption 98% or greater) in an acceptable period of time (i.e., 18 h or less) while maintaining high for the desired product (i.e., compound of Formula 1). While only one molar equivalent of amine versus the compound of Formula 2 is required by stoichiometry, typically, complete or near complete consumption of the compound of Formula 2 within 18 h or less is achieved using 5 to 10 molar equivalents within the temperature range of 80 °C and 120 °C. The product of the amination reaction (i.e., compound of Formula 1) may be isolated from the reaction mass by standard techniques well known to those skilled in the art. Since compounds of Formula 1 are typically solids at ambient temperature, they frequently crystallize from the reaction mass and are most easily isolated by filtration, optionally followed by washing with water and / or an organic solvent and drying. Addition of an “anti- solvent” may be useful to reduce the solubility of the product. For example, if the process is conducted in a water miscible organic solvent, such as acetonitrile, methanol or ethylene glycol, then addition of water typically increases the yield of crystallized product. The present method provides an efficient means to produce aminobenzamides of Formula 1 from anilines of Formula 3. The compounds of Formula 3 are generally known in the art and are commercially available or can be prepared from literature procedures. For example, a compound of Formula 3 wherein R1is CH3, R2is Cl and X is Br can be prepared as found in PCT Patent Publication WO 2008 / 051533 on page 93. A compound of Formula 3 wherein R1is CH3, R2is cyano and X is Br can be prepared as found in PCT Patent Publication WO 2010 / 093191 on pages 83 and 84.
