Reaction Steps

To (3S)-3-amino-1-[trans-4-({6-[2-(difluoromethyl)-1H-benzimidazol-1-yl]-2-(morpholin-4-yl)pyrimidin-4-yl}oxy)cyclohexyl]pyrrolidin-2-one (75 mg), triethylamine (22 μL), and dichloromethane (750 μL) was added methylchlorocarbonate (12 μL), followed by stirring at room temperature for 1 hour. After the completion of the reaction, a saturated aqueous sodium bicarbonate solution was added thereto, followed by extraction with chloroform. The organic layer was washed with saturated brine and then dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure. The residue was purified by silica gel column chromatography (chloroform:methanol) to obtain methyl{(3S)-1-[trans-4-({6-[2-(difluoromethyl)-1H-benzimidazol-1-yl]-2-(morpholin-4-yl)pyrimidin-4-yl}oxy)cyclohexyl]-2-oxopyrrolidin-3-yl}carbamate (55 mg) as a white powder.
