5-Fluoro-2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile

5-Fluoro-2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile (4-Cyano-2-fluoro-5-methylphenylboronic acid, pinacol ester) is a white to light-yellow powder or crystals

5-Fluoro-2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzonitrile can be used as a raw material to synthesize 4-(7-(1H-Pyrazol-4-yl)-2-(quinolin-4-ylamino)-[1,2,4]triazolo[1,5-a]pyridin-8-yl)-5-fluoro-2-methyl benzonitrile which is a pharmaceutically acceptable salt of inhibitor of cyclin-dependent kinase 2 (CDK2)
