반응 단계

To a solution of 3,4-(Methylenedioxy)aniline (8 g, 58.3 mmol) in AcOH (120 ml) was added Ac2O (48 mL). The mixture was stirred for overnight. After reaction, the mixture was poured into saturated NaHCO3 solution, and then filtered. The filtrate was extracted with ethyl acetate to give N-(benzo[d][1,3]dioxol-5-yl)acetamide (10 g, 95%). LCMS: 180 [M+1]+; 1H NMR (DMSO-d6) δ 2.0 (s, 3H), 5.96 (s, 2H), 6.82 (d, 1H, J=8.1 Hz), 6.91 (d, 1H, J=2.1 Hz), 7.30 (d, 1H, J=1.8 Hz), 9.84 (s, 1H).
