Reaction Steps

To a solution of 4-amino-2-chlorobenzotrifluoride (300 mg) and pyridine (243 mg) in dichloromethane (10 mL) was added a solution of trichloroacetyl chloride (279 mg) in dichloromethane (5 mL) dropwise. The solution was stirred for 2 hrs and then concentrated at reduced pressure. The residue was purified by silica gel chromatography eluting with 0-10% ethyl acetate in hexane to give the title compound as a white solid (360 mg, 69%).
