A solution of 4,6-dichloronicotinamide (400 mg, 2.09 mmol), 3-iodobenzylamine (0.285 mL, 2.13 mmol) and DIEA (0.500 mL, 2.87 mmol) in NMP (5 mL) was stirred at 90 C for 48 h. Water and EtOAc were added. Organic phase was separated, dried over Na2SO4, concentrated in vacuo. The residue was purified by a silica gel column, eluted with 0-100% EtOAc in hexane to give 6-chloro-4-(3-iodobenzylamino)nicotinamide as a solid (266 mg).
