Description

[0001] Citation of relevant applications

[0002] This application claims the full benefits of patent application No. 202110608943.2 filed with the State Intellectual Property Office of the People's Republic of China on June 1, 2021, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of medicinal chemistry. Specifically, this application relates to a hydrated crystal form of lazertinib methanesulfonate, its preparation method, and its uses. Background Technology

[0004] Polymorphism or polycrystalline phenomena are unique properties of certain molecules and molecular compositions. The same molecules may form different crystals due to different arrangements, and these crystals have different crystal structures and physical properties, such as solubility, stability, thermal properties, mechanical properties, purification ability, X-ray diffraction patterns, infrared absorption patterns, Raman spectroscopy, and solid-state NMR.

[0005] Discovering new crystal forms of pharmaceutical active ingredients (including anhydrous forms, hydrates, solvates, etc.) may result in substances with greater processing advantages or better physicochemical properties, such as better bioavailability, storage stability, ease of processing, ease of purification, or as intermediate crystal forms that promote conversion to other crystal forms. Certain specific crystal forms of compounds used as pharmaceutical active ingredients can also help improve drug performance. This expands the range of raw material options available in formulations, for example, by improving dissolution, extending shelf life, and facilitating processing.

[0006] Lazertinib (trade name LECLAZA) is a third-generation epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) developed by Yuhan Pharmaceuticals in South Korea. It targets the T790M mutation and activates EGFR mutations while preserving wild-type EGFR. This compound can be used as a drug to inhibit the activity of protein kinase-mediated disease, especially EGFR with one or more mutations compared to wild-type EGFR. Its IUPAC name is N-[5-[[4-[4-[(dimethylamino)methyl]-3-phenylpyrazol-1-yl]pyrimidin-2-yl]amino]-4-methoxy-2-morpholin-4-ylphenyl]prop-2-enamide, and its structural formula is shown in formula (I). Clinically, it is mainly used to treat metastatic non-small cell lung cancer, and is administered as a monomethylsulfonate salt of the compound of formula (I).

[0007]

[0008] The solid form of small molecule chemical drugs, i.e., different crystal forms, can result in different solubilities and stability, thereby affecting drug absorption and bioavailability, and even leading to differences in clinical efficacy. CN110869367A reports the crystalline form (I) of lazertinib monomethylsulfonate (hereinafter referred to as: crystal form I). The applicant prepared it according to the method of Example 1 of the patent application and found that the material could not react completely. After improving the preparation method, although crystal form I was successfully obtained, the sample of crystal form I changed color, impurities increased, and the stability was poor during accelerated stability studies, making it unsuitable for long-term storage.

[0009] Therefore, there is still a need in the field for a new crystal form of lazertinib monomethylsulfonate that is highly soluble, stable, and suitable for storage, in order to facilitate the development, production, and storage of lazertinib. Summary of the Invention
