Procedure

To 5-cyclopropyl-2-(4-fluorophenyl)-N-methyl-6-(N-(3-methyl-4-nitrophenyl)methylsulfonamido)benzofuran-3-carboxamide (2.0 g, 3.72 mmol) in Ethanol (10 mL) and THF (2 mL), Pd/C (0.396 g) was added and subjected to hydrogenation at RT for 12 h. The reaction mixture was filtered through Celite. The solvent was evaporated under reduced pressure to afford the title compound in 86% yield. 1H NMR (400 MHz, DMSO-d6) δ ppm: 7.85-7.95 (m, 1H), 7.67-7.73 (m, 1H), 7.37-7.42 (m, 1H), 7.11-7.26 (m, 1H), 6.59-6.68 (m, 1H), 5.86 (br. s., 1H), 3.18 (s, 1H), 2.99 (s, 2H), 2.10-2.17 (m, 1H), 1.37-1.51 (m, 1H), 1.08-1.19 (m, 1H), 0.91-1.06 (m, 1H), 0.45-0.92 (m, 1H). LCMS (m/z, ES+)=508 (M+H+).
