実験手順

Acetic anhydride (6.5 mL) was added slowly to a stirred solution of 3,5-dimethoxy aniline (10 g, 65.359 mmol) in toluene (50 mL) under argon atmosphere at room temperature and resulting reaction mixture was stirred for 15 h. After completion of the reaction, reaction was diluted with Hexane and resulted precipitate was collected by filtration and dried under vacuum to afford the title compound (12.5 g, 98% of yield) as a off-white solid. 1HNMR (CDCl3, 300 MHz): δ 7.38 (s, 1H), 6.75 (d, 2H), 6.23 (s, 1H), 3.76 (s, 6H), 2.15 (s, 3H); MS (ESI): 196.1 [M+H]+.
