Procedure

A solution of 5-cyclopropyl-6-(N-(3-(difluoromethyl)-4-nitrophenyl)methylsulfonamido)-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (1.45 g, 2.53 mmol) and 10% Pd/C (catalytic) in MeOH (15 mL) was stirred under a hydrogen atmosphere (20 psi) for 3 h. The reaction mixture was filtered through celite, evaporated, and purified by silica gel chromatography (0-50% EtOAc/hexanes) to afford the title compound (0.87 g, 63%) as a white solid. LCMS (m/z, ES+)=544.3 (M+H+).
