Reaction Steps

trans-4-({6-[2-(Difluoromethyl)-1H-benzimidazol-1-yl]-2-(morpholin-4-yl)pyrimidin-4-yl}amino)cyclohexanecarboxylic acid (232 mg) was dissolved in tetrahydrofuran (2.3 mL), and isobutyl chloroformate (70 μL) and 4-methylmorpholine (60 μL) were added thereto at 0° C., followed by stirring at 0° C. for 30 minutes and at room temperature for 2 hours. Subsequently, 28% aqueous ammonia (300 μL) was added thereto at 0° C., followed by stirring for 2 hours. The solvent was evaporated under reduced pressure and purified by silica gel chromatography (hexane:ethyl acetate=40:60-0:100 and chloroform:methanol-100:0-95:5) to obtain trans-4-({6-[2-(difluoromethyl)-1H-benzimidazol-1-yl]-2-(morpholin-4-yl)pyrimidin-4-yl}amino)cyclohexanecarboxamide (230 mg).
