Reaction Steps
A mixture of thiophen-2-ylmethanamine (600 mg, 5.30 mmol), DMAP (130 mg, 1.06 mmol, 0.2 equiv) and acetic anhydride (648 mg, 6.36 mmol, 1.2 equiv) in DCM (20 mL) was stirred at room temperature for 2 h. Water was added and the reaction was extracted with EA. The combined organic layers were dried (Na2SO4), filtered. The filtrate was concentrated to afford the compound N-(thiophen-2-ylmethyl)acetamide (745 mg, 91%). LC-MS (m/z)=156 [M+H]+.
