Problems solved by technology

[0005] The crystal form has a certain influence on the physical and chemical properties of the compound. For pharmaceutical compounds with multiple crystal forms, different crystal forms may have different appearances such as color and shape, and certain physical and chemical properties such as melting point and solubility. , density, stability, hygroscopicity, etc. will also be different, which will lead to different dissolution and absorption behaviors in the body, which will affect the quality stability, clinical efficacy and safety of raw materials and preparations to a certain extent

Embodiment 1

[0055] Embodiment 1 Preparation of crystal form of compound of formula (I)

[0056] Add formula (I) compound N-{2-{[2-(dimethylamino)ethyl](methyl)amino}-6-(2,2,2-trifluoroethane) to a 250mL three-necked flask Oxy)-5-{[4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl]amino}pyridin-3-yl}acrylamide 10.0g, add acetone 140mL, magnetic Stir, protect with argon, heat up in an oil bath to 50-56°C to completely dissolve the solid, continue to keep warm and stir for 20 minutes after dissolving, then add 70mL of n-heptane dropwise over 40 minutes, and naturally cool down to 38°C in the oil bath , and crystallized at 38°C for 30 minutes, then naturally cooled to 20°C in an oil bath and continued to stir and crystallize for 1 hour, filtered with suction, rinsed with n-heptane, dried in a vacuum oven at 50°C for 48 hours, and weighed to obtain the formula ( I) Compound crystal form 6.38g, yield 63.8%.

[0057] Its XRPD spectrum, DSC spectrum, TGA spectrum are respectively as follows figure 1 , ...

Embodiment 2

[0060] Embodiment 2 Preparation of crystal form of compound of formula (I)

[0061] Add formula (I) compound N-{2-{[2-(dimethylamino)ethyl](methyl)amino}-6-(2,2,2-trifluoroethane) to a 100mL three-necked flask Oxy)-5-{[4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl]amino}pyridin-3-yl}acrylamide 3.0g, add tetrahydrofuran 15mL, magnetic Stir, protect with argon, heat up to 40-45°C in an oil bath to completely dissolve the solid, keep stirring for 10 minutes after dissolution, then add 30 mL of n-heptane dropwise over 15 minutes, keep warm and crystallize at 40-45°C After 18 hours, the temperature was naturally lowered to 20°C in an oil bath and continued to stir and crystallize for 2 hours, then suction filtered and rinsed with n-heptane. It was dried in a vacuum oven at 50° C. for 48 hours, weighed 2.67 g, and the yield was 89%. Its XRPD, DSC, and TGA spectra are basically consistent with the results of Example 1.

Embodiment 3

[0062] Embodiment 3 Preparation of crystal form of compound of formula (I)

[0063] Add formula (I) compound N-{2-{[2-(dimethylamino)ethyl](methyl)amino}-6-(2,2,2-trifluoroethane) to a 250mL three-necked flask Oxy)-5-{[4-(1-methyl-1H-indol-3-yl)pyrimidin-2-yl]amino}pyridin-3-yl}acrylamide 10.0g, add tetrahydrofuran 50mL, magnetic Stir, protect with argon, heat up to 40-45°C in an oil bath to completely dissolve the solid, continue to heat and stir for 15 minutes after dissolving, then add 150mL of methyl tert-butyl ether dropwise over 2 hours, at 40-45°C Insulated and crystallized for 18 hours, then naturally cooled to 20°C in an oil bath and continued to stir and crystallize for 2 hours, filtered with suction, and rinsed with methyl tert-butyl ether. Dry in a vacuum oven at 50° C. for 48 hours, weigh 6.3 g, and yield 63%. Its XRPD, DSC, and TGA spectra are basically consistent with the results of Example 1.
