Reaction Steps
To a suspension of 2-bromo-1-[4-(methylsulfonyl)phenyl]ethanone (0.27 g, 1 mmol) and 4-(3-thienyl)phenylacetic acid (0.19 g, 0.9 mmol) in acetonitrile (5 mL) was added Et3N (0.33 mL) at 0° C. under nitrogen. After stirring for 20 minutes at room temperature, the mixture was chilled in ice bath. DBU (0.29 mL) was added to the mixture, and stirred for 20 minutes at 0° C. To the mixture was added 1N HCl solution (8 mL) and ice-water (10 mL), and the mixture was stirred for 2 minutes. The whole was extracted with CH2Cl2 (50 mL×3), the combined organic layer washed with brine, dried over MgSO4, and concentrated in vacuo. The residue was purified by flash chromatography eluting with ethyl acetate/hexane (1/1) followed by recrystallization from ethyl acetate/hexane to provide the title compound (0.15 g, 39% yield).
