Participants

Reaction Steps

2 N Sodium hydroxide solution (0.25 mL, 0.5 mmol) was added dropwise to a stirred solution of methyl-3-(4′-dibenzofuran-4-yl-biphen-4ylmethylsulfanyl)-2(2-fluoro-5-trifluoromethylbenzoylamino)-propionate (110 mg, 0.17 mmol) in tetrahydrofuran (5 mL) and methanol (1 mL). The clear reaction mixture was stirred at room temperature until the reaction was complete (TLC control), and then diluted with water (5 mL), and acidified to pH 3 with 2 N hydrochloric acid. The reaction mixture was extracted with ethyl acetate (2×10 mL). The combined extract was washed with water, sat'd aq NaCl, dried over anhydrous MgSO4, filtered and concentrated in vacuo. Purification by flash column chromatography (5-10% methanol in methylene chloride) afforded the title compound has a white solid (98 mg).
