실험 절차

Triethylamine (6.5 g, 64.2 mmol) was added to a stirred solution of 4-amino-2-[(trifluoromethyl)oxy]benzonitrile (Intermediate 51, 6.5 g, 32.2 mmol) in DCM (100 mL) at 0° C. and the mixture was stirred for 15 min. Chloro-2-oxoethyl acetate (5.2 g, 38.1 mmol) was added at 0° C. and stirring was continued for 4 hr at room temperature. The reaction mixture was diluted with DCM and washed with ice-water, saturated aq. NaHCO3 solution and brine solution, dried over anhydrous Na2SO4 and concentrated under reduced pressure to afford the crude product. This was purified by column chromatography (100-200 mesh silica gel), eluting with 30% EtOAc/pet ether to give the title compound (8.10 g).
