실험 절차
4-(3-Bromo-4-methoxy-phenyl)-4-methyl-3-oxo-pentanoic acid ethyl ester (Compound K3, 10.3 g, 30.01 mmol) was dissolved in DMF (80 mL), added with cesium carbonate (24.4 g, 2.5 eq.) and 4-chloro-3-nitro-benzonitrile (7.12 g, 1.3 eq.), and then stirred at 45° C. for 4 hr. The reaction solution was added to 1 N aqueous solution of hydrochloric acid, and extracted with ethyl acetate. The organic layer was washed with saturated brine and dried over sodium sulfate. The drying agent was removed by filtration, and after concentration under reduced pressure the title compound was obtained as a crude product (yellow oily substance).
