Acetic Acid → 6-Chloro-4-(thiophen-2-ylmethylamino)nicotinamide

Participants

Reaction Steps

To a solution of ethyl 6-chloro-4-(thiophen-2-ylmethylamino)nicotinate (1.54 g, 5.19 mmol) in DMF (8 mL) and HCONH2 (2 mL, 50.3 mmol), NaOEt (21% by wt., 7.80 mL, 20.9 mmol) in EtOH was added. The mixture was stirred at room temperature for 20 min. HOAc (2 mL) was added to neutralize NaOEt. Water was then added to induce precipitation. The precipitate was collected, dried on vacuum to give 6-chloro-4-(thiophen-2-ylmethylamino)nicotinamide as a solid (1.10 g).
