Procedure

To a 25 mL round-bottomed flask was added methyl 2′-carbamoyl-4-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)biphenyl-2-carboxylate (58.3 mg, 0.107 mmol), methanol (1 mL), THF (1 mL) and 8 equivalents of a 1M solution of sodium hydroxide (0.856 mL, 0.856 mmol). The mixture was diluted with 20 mL of ethyl acetate, made acidic with 0.5M HCl and the crude product was extracted, washed with brine, and dried over sodium sulfate. The product solution was filtered and evaporated to dryness giving 52 mgs (98% yield) of 2′-carbamoyl-4-(2-(4-fluorophenyl)-3-(methylcarbamoyl)benzofuran-5-yl)biphenyl-2-carboxylic acid as a yellow solid. The LC/MS data was obtained on a Shimadzu analytical LC/MICROMASS® Platform LC (ESI+) at 220 nm using the following set of conditions: PHENOMENEX® Luna 3 μm C18, 2×50 mm column, with a gradient of 0-100% B (B=90% HPLC grade acetonitrile/0.1% trifluoroacetic acid/10% HPLC grade water), (A=90% HPLC grade water/0.1% trifluoroacetic acid/10% HPLC grade acetonitrile), in 4 minutes with a 1 minute hold at a rate of 0.8 mL/minute. LCMS m/z 509.3 (M+H), Rt=2.695 min., 90% purity.
