[0030] "Organomagnesium compounds" are organometallic compounds in which the metal is magnesium.
[0031] The compounds of the present invention may contain one or more chiral carbon atoms. Therefore, the compounds may exist as diastereomers, enantiomers, or mixtures thereof. Racemic compounds, diastereomers, or enantiomers may be used as starting materials or intermediates in the synthesis of the compounds. A mixture of specific diastereomer compounds may be separated or concentrated into one or more specific diastereomers by chromatography or crystallization. Similarly, enantiomixtures may be separated or enantiomerically concentrated using the same technique or other techniques known in the art. Each of the asymmetric carbon or nitrogen atoms may be present in the R or S configuration, and both of these configurations are within the scope of the present invention.
[0032] In the structures shown herein, if the stereochemistry of any specific chiral atom is not specified, all stereoisomers are conceived and included as compounds of the present invention. Where stereochemistry is indicated by a solid wedge or dashed line representing a specific configuration, the stereoisomers are indicated and defined in that way. Unless otherwise stated, relative stereochemistry is intended when solid wedges or dashed lines are used.
[0033] The term "stereoisomer" refers to compounds that have the same chemical structure but differ in the arrangement of atoms or groups in space. Stereoiomers include diastereomers, enantiomers, atropisomers, and conformational isomers.
[0034] The term "chiral" refers to molecules that have the property of not being able to be superimposed on their mirror image partners, while the term "achiral" refers to molecules that can be superimposed on those mirror image partners.
[0035] The term "diastereomer" refers to stereoisomers that have two or more chiral centers and whose molecules are not mirror images of each other. Diastereomers have different physical properties, such as melting point, boiling point, spectroscopic properties, or biological activity. Mixtures of diastereomers can be separated under high-resolution analytical procedures such as electrophoresis and chromatography such as HPLC.
[0036] The term "enantiomer" refers to two stereoisomers of a compound that are mirror images of each other but cannot be superimposed.
[0037] Atropisomers are stereoisomers resulting from rotations that are sterically hindered by a single bond or axis, where steric strain or other factors create a rotational barrier that is high enough to allow for the isolation of individual conformational isomers.
[0038] The stereochemical definitions and conventions used in this specification generally follow those of SP. Parker, Ed., McGraw-Hill Dictionary of Chemical Terms (1984), McGraw-Hill Book Company, New York, and Eliel, E. and Wilen, S., “Stereochemistry of Organic Compounds”, John Wiley & Sons, Inc., New York, 1994. Many organic compounds exist in optically active forms, that is, they have the ability to rotate the plane of plane-polarized light. When describing optically active compounds, the prefixes D and L, or R and S, are used to indicate the absolute configuration of the molecule around its chiral center(s). The prefixes d and l, or (+) and (-), are used to indicate the sign of the rotation of plane-polarized light by the compound, with (-) or l meaning that the compound is levorotatory. Compounds with the prefix (+) or d are dextrorotatory. In a given chemical structure, these stereoisomers are identical except that they are mirror images of each other. Furthermore, certain stereoisomers are sometimes called enantiomers, and mixtures of such isomers are often called enantiomer mixtures. A 50:50 mixture of enantiomers is called a racemic mixture or racemate, which can occur when there is no stereoselectivity or stereospecificity in a chemical reaction or method. The terms "racemic mixture" and "racemate" refer to equimolar mixtures of two enantiomer species that are not optically active.
[0039] The term "tautomer" or "tautomer" refers to structural isomers with different energies that are interconvertible via a low-energy barrier. For example, proton tautomers (also known as prototropic tautomers) include interconversions by proton rearrangement, such as keto-enol and imine-enamine isomerization. Valence tautomers include interconversions by rearrangement of several bonding electrons.
[0040] As used herein, the term “amino protecting group” means a derivative of a group commonly used to block or protect an amino group. The reaction, on the other hand, takes place at another functional group of the compound. Examples of such protecting groups include carbamates, amides, alkyl and aryl groups, as well as imines, and many N-heteroatom derivatives that can be removed to regenerate the desired amine group. Specific amino protecting groups include PMB (p-methoxybenzyl), Boc (tert-butyloxycarbonyl), Fmoc (9-fluorenylmethyloxycarbonyl), Cbz (carbobenzyloxy), Ac (acetyl), trifluoroacetyl, phthalimide, Bn (benzyl), Tr (triphenylmethyl or trityl), benzylidenyl, p-toluenesulfonyl, or DMB (dimethoxybenzyl). In some embodiments, the amino protecting group may be a group used to block or protect an amino group, arising from the cyclization of a group bonded to the amino group, but which can later be removed or substituted. Examples of such groups include 1,3,5-dioxazinane, 2,4-dimethyl-1,3,5-dioxazinane, 2,2,5,5-tetramethyl-1,2,5-azadisyloridine, and isoindoline-1,3-dione. Further exemplary amino protecting groups are described in TWGreene and PGMWuts, "Protecting Groups in Organic Synthesis, Vol. 3." 版 This is found in John Wiley & Sons, Inc., 1999. The term "protected amino" refers to an amino group that has been substituted with one of the above amino protecting groups.
[0041] The term "leaving group" refers to a part of a first reactant that is replaced in a chemical reaction. Examples of leaving groups include, but are not limited to, halogen atoms, alkoxys, and sulfonyloxy groups. Exemplary sulfonyloxy groups include, but are not limited to, alkylsulfonyloxy groups (e.g., methylsulfonyloxy (mesylate group) and trifluoromethylsulfonyloxy (triflate group)) and arylsulfonyloxy groups (e.g., p-toluenesulfonyloxy (tosylate group) and p-nitrosulfonyloxy (nosylate group)).
[0042] The terms “inhibit” and “reduce / decrease,” or any variation thereof, include any measurable reduction / decrease or complete inhibition to achieve the desired result. For example, there may be a reduction of approximately, at most approximately, or at least approximately 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 99%, or more, or any range of these variables, a decrease in activity compared to normal.
[0043] The terms “antagonist” and “inhibitor” are used interchangeably and refer to compounds that have the ability to inhibit the biological function of a target protein, whether by inhibiting the activity or expression of the protein, such as K-Ras, H-Ras, or N-Ras G12C. Therefore, the terms “antagonist” and “inhibitor” are defined in the context of the biological role of the target protein. Preferred antagonists in this specification are those that specifically interact with the target (e.g., by binding to the target), while compounds that inhibit the biological activity of the target protein by interacting with other elements of the signaling pathway in which the target protein is an element are also specifically included within this definition. Preferred biological activities inhibited by antagonists are those associated with tumor progression, growth, or expansion.
[0044] As used herein, the term “agonist” means a compound that has the ability to initiate or enhance the biological function of a target protein, whether by inhibiting the activity or expression of the target protein. Therefore, the term “agonist” is defined in the context of the biological role of the target polypeptide. Preferred agonists as used herein are those that specifically interact with the target (e.g., by binding to the target), while compounds that initiate or enhance the biological activity of the target polypeptide by interacting with other elements of a signaling pathway in which the target polypeptide is an element are also specifically included within this definition.
[0045] The terms “cancer,” “malignant,” “neoplasm,” and “tumor,” as well as related terms, refer to or describe a physiological condition in mammals typically characterized by the uncontrolled growth of cells. A “tumor” contains one or more cancer cells. Examples of cancer include carcinoma, blastoma, sarcoma, seminoma, gliablastoma, melanoma, leukemia, and myeloid or lymphoid malignancies. More specific examples of such cancers include squamous cell carcinoma (e.g., epithelial squamous cell carcinoma) and lung cancer (such as small cell lung cancer, non-small cell lung cancer ("NSCLC"), lung adenocarcinoma, and lung squamous cell carcinoma). Other cancers include skin cancer, keratoacanthoma, follicular carcinoma, pilocytic cell leukemia, oral cancer, pharyngeal cancer, lip cancer, tongue cancer, mouth cancer, salivary gland cancer, esophageal cancer, laryngeal cancer, hepatocellular carcinoma, gastric cancer, stomach cancer, gastrointestinal cancer, small intestine cancer, colorectal cancer, pancreatic cancer, cervical cancer, ovarian cancer, liver cancer, bladder cancer, breast cancer, colon cancer, rectal cancer, colorectal cancer, genitourinary cancer, biliary tract cancer, thyroid cancer, papillary cancer, liver cancer, endometrial cancer, uterine cancer, salivary gland cancer, kidney cancer or renal cancer, prostate cancer, testicular cancer, vulvar cancer, peritoneal cancer, anal cancer, penile cancer, bone cancer, multiple myeloma, B-cell lymphoma, diffuse large B-cell lymphoma (DLBCL), central nervous system cancer, brain cancer, head and neck cancer, Hodgkin's disease, and associated metastases. Examples of neoplastic disorders include myeloproliferative disorders such as polycythemia vera, myelofibrosis such as essential thrombocytosis and primary myelofibrosis, and chronic myeloid leukemia (CML).
[0046] A “chemotherapeutic agent” is an active substance useful for treating a given disorder, such as cancer or an inflammatory disorder. Examples of chemotherapeutic agents are known in the prior art and include, for example, those disclosed in U.S. Patent Application Publication No. 2010 / 0048557, which is incorporated herein by reference. Furthermore, chemotherapeutic agents include pharmaceutically acceptable salts, acids, or derivatives of any of the chemotherapeutic agents, and combinations of two or more thereof.
[0047] The term “treatment” refers to a clinical intervention designed to alter the natural course of a patient or cell being treated during the course of a clinical lesion. Desired effects of treatment include a reduction in the rate of disease progression, recovery or mitigation of the disease state, and remission or improvement of the prognosis. A patient’s “treatment” is considered successful if one or more of the breast cancer-related symptoms described herein are reduced or eliminated, including, for example, a decrease (or destruction) of cancer cell proliferation, a reduction in disease-related symptoms, an improvement in the quality of life of the person affected by the disease, a reduction in the dose of other medications required to treat the disease, and / or an extension of the patient’s survival.
[0048] The term “delaying the progression” of a disease means delaying, preventing, slowing, stabilizing, and / or postponing the development of breast cancer as described herein. This delay may be of varying lengths depending on the patient’s cancer history and / or the patient being treated. As will be apparent to those skilled in the art, a sufficient or significant delay may substantially encompass prevention in that the patient does not develop cancer.
[0049] "Effective dose" means the minimum amount required to produce a measurable improvement or prevention of breast cancer as described herein. The effective dose as described herein may vary depending on factors such as the patient's disease status, age, sex and weight, and the ability of the active ingredient to induce the desired response in the patient. The effective dose is also the amount in which the therapeutically beneficial effect outweighs any toxic or adverse effects of the treatment. Beneficial or desired outcomes include the elimination or reduction of risk, reduction of severity, delay in the onset of the disease (including the biochemical, histological and / or behavioral symptoms of the disease, its complications and intermediate pathological phenotypes that appear during the onset of the disease), reduction of one or more symptoms caused by the disease, improvement in the quality of life of the person with the disease, reduction in the dose of other drugs required to treat the disease, enhancement of the effect of another drug by targeting, etc., delay in disease progression, and / or extension of survival. In some embodiments, an effective dose of a drug may be effective in reducing the number of cancer cells; shrinking tumor size; inhibiting (i.e., delaying or stopping) cancer cell invasion into peripheral organs; inhibiting (i.e., delaying or stopping) tumor metastasis; inhibiting (i.e., delaying or stopping) tumor growth; and / or alleviating one or more symptoms associated with the disorder. An effective dose may be administered in one or more doses. An effective dose of a drug, compound, pharmaceutical composition or combination therapy described herein may be sufficient to achieve a therapeutic action directly or indirectly. As clinically understood, an effective dose of a drug, compound or pharmaceutical composition may or may not be achieved in combination with another drug, compound or pharmaceutical composition or combination therapy. Thus, “effective dose” may be considered in the context of administering one or more therapeutic agents, and a single agent may be considered an effective dose if, in combination with one or more other agents, the desired result is obtained or achieved.
[0050] It is conceivable that any limitation discussed in relation to one embodiment of the present invention may also apply to any other embodiment of the present invention. Furthermore, any compound or composition of the present invention may be used in any manner of the present invention, and any compound or composition of the present invention may be produced or utilized using any manner of the present invention.
[0051] Throughout this application, the term “approximately” is used to indicate that the value includes the standard deviation of errors in the device or method used to measure that value.

After stirring for 30 minutes, DMF (2.0 equivalents) was added over at least 3 hours. After aging for 1 hour (IPC conversion rate > 97.5% a / a), the mixture was added all at once to a chilled solution (0°C) of citric acid (1.2 equivalents) in water (1 Veq.). The mixture was heated to 45°C and the aqueous phase was separated.
[0192] Process 2
[0193] To the organic phase containing 4b, hydroxylamine (1.05 equivalents, 50% wt in water) was added at 45°C for at least 1 hour. After stirring for 30 minutes (IPC conversion > 98.8% - a / a), saline solution (100 mL) was added at the same temperature. The aqueous phase was separated, and the organic phase was concentrated to a total volume of 200 mL by vacuum distillation. Vacuum distillation was then carried out under constant volume by supplying acetic acid (200 mL). After adjusting the solution to 70°C, water (100 mL) was added over at least 30 minutes, and the seed was introduced.

[0204] Step 8:
[0205] Subsequently, the solution from step 7 was telescoped and cooled to 25°C, and (S)-1-Boc-3-methylpiperazine (34.1 g) was added in five portions over at least 1 hour. After stirring for 30 minutes, DIPEA (24.2 g) was added within 1 hour, and the resulting suspension was stirred for 30 minutes (IPC: 5a < 0.4% - a / a). The mixture was heated to 40°C and stirred for 1 hour, after which heptane was added over at least 1 hour. After stirring for another 1 hour at 40°C, the suspension was cooled to 25°C over at least 1 hour and aged for at least 2 hours.

[0221] Compound 2b was recovered into a receiving tank using an intra-tube (IT) at 0-30°C. Compound 2b was found to be stable for several weeks at -20-30°C.
[0222] Five different experiments were conducted in which the equivalent amounts of ZnCl2 and compound 2a were varied from 0.33, 0.50, 0.75, and 1.00-1.50. 19 1F NMR revealed the presence of three different species / compounds at varying levels depending on the amount of ZnCl2 used. 2D NOESY demonstrated that these species can be interconverted without significantly affecting the dynamics of the resulting sedge.
[0223] Des-bromo-compound 2a was found as another compound present in the spectrum, and it originates from a proton quenching reaction caused by residual water in the NMR solvent.
