Acetic Anhydride → N-(3,5-dimethoxyphenyl)acetamide

Participants

Reaction Steps

To a solution of 3,5-dimethoxy-phenylamine (20 g, 0.131 mol) in toluene (110 mL) was added acetic anhydride (14 g, 0.137 mmol) at room temperature. The resulting mixture was stirred for 18 hours at room temperature. PE (55 mL) was added, the precipitate was filtered and washed with PE (100 mL) to obtain the title compound (24.2 g, yield: 95%). 1H-NMR (400 MHz, CDCl3) δ 2.16 (s, 3H), 3.77 (s, 6H), 6.23 (s, 1H), 6.75 (s, 2H), 7.20 (s, 1H).
