反応手順

To a solution of aniline 46 (500 mg, 0.948 mmol) in DCM (10 ml) was added 2,4-difluoro-1-isocyanatobenzene (441 mg, 3 eq, 2.84 mmol) and the reaction mixture was stirred at RT for 24 hours. The mixture was concentrated and purified via column chromatography (eluent 10% MeOH in EtOAc) to afford 350 (600 mg, 93%) as a white solid. MS (m/z)=683.7 (M+H)
