Abstract

The invention provides a novel crystal form of (1S, 4R)-N-((S)-1-(6-(4-fluoro-1H-pyrazol-1-yl) pyridine-3-yl) ethyl)-1-methoxy-4-(4-methyl-6-((5-methyl-1H-pyrazol-3-yl) amino) pyrimidine-2-yl) cyclohexane formamide (a compound represented by a formula (I)) and a preparation method thereof.

Description

technical field [0001] The present invention relates to the field of medicinal chemistry, in particular to (1S,4R)-N-((S)-1-(6-(4-fluoro-1H-pyrazol-1-yl)pyridin-3-yl)ethyl) -New crystal form of 1-methoxy-4-(4-methyl-6-((5-methyl-1H-pyrazol-3-yl)amino)pyrimidin-2-yl)cyclohexanecarboxamide and its preparation method. Background technique [0002] RET (Rearranged during transfection) is a relatively rare proto-oncogene, which is located on the long arm of human chromosome 10 and encodes a receptor tyrosine kinase. The receptor spans both sides of the cell membrane and completes signal transduction by forming a protein complex. RET protein plays an important role in the development of kidney and gastrointestinal system. In a variety of cancers, alterations in the RET gene lead to activation of kinases that drive tumor formation and growth. Initially, it was discovered that RET gene alterations were associated with the occurrence of papillary thyroid carcinoma; recent studies...
