Reaction Steps

Add 4-chloro-3-(trifluoromethyl)aniline (1.0 g, 5.1 mmol) and pyridine (1.0 g, 12.8 mmol) in DCM (10 mL), stir well and cool to 0° C. Add phenyl chloroformate (1.04 g, 6.6 mmol) at 0° C. After addition, stir the reaction at room temperature for 1 hr. TLC (EtOAc:PE=1:2) shows the reaction is complete. Wash the organic layer with 1M HCl solution (20 mL) and brine (20 mL) respectively. Dry over anhydrous Na2SO4; concentrate under reduced pressure to give the target compound (1.16 g) which is used without further purification. MS: (M+1): 316.1.
