Abstract

The invention discloses a crystal form I of an alkyne group-containing compound, a preparation method and an application thereof. The present invention specifically discloses a 3-((1H-pyrazol[3,4-b]pyridine-5-substituted)ethynyl)-4-methyl-N-(4-((4-methylpiperazine -1-substituted)methyl)-3-(trifluoromethyl)phenyl)benzamide Form I. The crystal form of the invention has good stability and is of great value to the optimization and development of medicines.

Description

technical field [0001] The invention belongs to the field of chemistry and medicine, and in particular relates to a crystal form I of an alkyne group-containing compound, a preparation method and application thereof. Background technique [0002] The application relates to an alkynyl-containing compound, the chemical name is 3-((1H-pyrazol[3,4-b]pyridine-5-substituted)ethynyl)-4-methyl-N-(4-(( 4-Methylpiperazine-1-substituted)methyl)-3-(trifluoromethyl)phenyl)benzamide, the report on this compound in the patent is very limited and does not involve the crystal form of the above compound. [0003] It is known that polymorphism commonly exists in compounds, and general drugs may exist in two or more different crystal forms. The existing form and quantity of polymorphic compounds are unpredictable. Different crystal forms of the same drug have significant differences in solubility, melting point, density, stability, etc., which affect the temperature profile, uniformity, and bi...
