Reaction Steps

Add 3-(trifluoromethoxy)aniline (1.0 g, 5.65 mmol), pyridine (0.89 g, 11.3 mmol) to DCM (20 mL) and cool to 0° C. Add dropwise phenyl chloroformate (1.15 g, 7.34 mmol). After addition, stir for 1 hr. TLC (PE:EtOAc=3:1) shows the reaction is complete. Add water to the mixture, extract with DCM (10 mL×3), combine the organic layer, wash with 1N HCl solution, brine sequentially, and dry over anhydrous Na2SO4. Concentrate under reduced pressure to get the product (1.50 g, 89%).
