실험 절차

To a solution of 2-(4-hydroxy-3-methylphenyl)-2-methyl-1-{3-methyl-5-[4-(trifluoromethyl)phenyl]thien-2-yl}propan-1-one (intermediate 105, 62.0 mg) in anhydrous acetonitrile (2 ml) was added caesium carbonate (106 mg) and ethyl bromoacetate (18 μl) and the reaction stirred at room temperature under nitrogen for 20 hours. The solid residue was filtered, and the filtrate was concentrated in vacuo and the residue purified by flash column chromatography, eluting with 1% EtOAc/cyclohexane yielded the title compound as a white solid.
