Procedure
To a solution of 5-cyclopropyl-2-(4-chlorophenyl)-6-(methylsulfonamido)benzofuran-3-carboxylic acid (5 g, 11.52 mmol) in dry DMF (30 mL) was added DIPEA (3.3 g, 25.34 mmol) and HATU (5.15 g, 13.5 mmol) at 20° C. After 15 minutes, 2M Methylamine in THF (23.04 mL, 46.08 mmol) was added dropwise and the mixture was stirred for another 2 hours before water (60 mL) was added. The mixture was extracted with EA (3×200 mL), washed with water (2×200 mL), dried and concentrated to afford 2-(4-Chlorophenyl)-5-cyclopropyl-N-methyl-6-(methylsulfonamido)benzofuran-3-carboxamide as a brown solid (4.7 g, 97%). 1H NMR (400 MHz, DMSO-d6) δ ppm 9.32 (br. s., 1H) 8.45 (q, 1H) 7.90 (d, 2H) 7.53-7.64 (m, 3H) 7.16 (s, 1H) 3.06 (s, 3H) 2.83 (d, 3H) 2.21-2.37 (m, 1H) 0.94-1.05 (m, 2H) 0.64-0.73 (m, 2H). LCMS (m/z, ES+)=419 (M+H+).
