Reaction Steps
A solution of 4,6-dichloronicotinamide (123 mg, 0.643 mmol), thiophen-2-ylmethanamine (0.065 mL, 0.634 mmol) and DIPEA (0.230 mL, 1.32 mmol) in NMP (4 mL) was stirred at 90 C for 18 h. Water and EtOAc were added. The organic phase was separated, dried over Na2SO4, and concentrated in vacuo to give 6-chloro-4-(thiophen-2-ylmethylamino)nicotinamide as a solid (168 mg).
