Procedure

A mixture of 5-cyclopropyl-2-(4-fluorophenyl)-N-methyl-6-[(methylsulfonyl)amino]-1-benzofuran-3-carboxamide (500 mg, 1.24 mmol), 3-bromophenylboronic acid (1.5 g, 7.46 mmol), copper(II) acetate monohydrate (372 mg, 1.87 mmol), triethylamine (252 mg, 2.49 mmol), 4 Å molecular sieves (1 g) in dichloromethane (160 mL) was stirred for 2 days. The solid was filtered off, the filtrate was concentrated to dryness and purified by column chromatography to afford 6-(N-(3-bromophenyl)methylsulfonamido)-5-cyclopropyl-2-(4-fluorophenyl)-N-methylbenzofuran-3-carboxamide (270 mg, 0.48 mmol, 39% yield) as a brown solid. LCMS (m/z, ES+)=557, 559 (M+H+).
