反応手順

To a solution of aniline 46 (300 mg, 0.569 mmol) in DCM (10 mL) at 0° C. was added DIPEA (0.199 mL, 1.137 mmol) and 2-fluorobenzoyl chloride (135 mg, 0.853 mmol) and the suspension was stirred overnight at room temperature. The reaction mixture was concentrated and the residue was partitioned between EtOAc and water. The organic layer was collected, dried and concentrated. The residue was purified using Biotage (eluent EtOAc, 25 g Silicycle HR column) to provide the title compound 356 (400 mg, 0.616 mmol, quantitative yield) as a white solid.
