To a solution of 4,4-difluorocyclohexanamine hydrochloride (Matrix scientific, 250 mg, 1.45 mmol) in DCM (5 mL) was added 4-nitrophenyl chloroformate (367 mg, 1.82 mmol) and DIEA (507 μl, 0.29 mmol). The resulting mixture was then stirred at RT for 16 h. Then, MeOH (2 mL) was added and the solvents were removed. The residue was purified by silica gel flash column chromatography (0%-100% EtOAc/hexane) to give the title compound as a yellow solid.
