2′-Methyl-5′-[(2-pyrrolidin-1-ylisonicotinoyl)amino]-1,1′-biphenyl-4-carboxylic acid (40 mg, 0.1 mmol), HATU (38 mg, 0.1 mmol), HOBT (13 mg, 0.1 mmol), DIPEA (52 μl), and 4-methoxyaniline (15 mg, 0.12 mmol) were mixed in DMF (1 ml) and stirred at room temperature for 18 h. The solvent was evaporated under vacuum and the residue partitioned between DCM (5 ml) and aqueous sodium carbonate (1M, 5 ml). The organic phase was applied to a silica gel flash column and eluted with DCM/ethanol/ammonia (400:8:1 then 300:8:1), which, after evaporation of the solvents under vacuum, gave N-{4′[(4-methoxyanilino)carbonyl]-6-methyl-1,1′-biphenyl-3-yl}-2-pyrrolidin-1-ylisonicotinamide (16 mg, 30%).
