Potassium Hydroxide → 2-Chloro-3,5-Dimethoxyaniline

関与物質

反応手順

Potassium hydroxide (2.19 g, 39.18 mmol) was added to a solution of N-(2-chloro-3,5-dimethoxyphenyl)acetamide (1.8 g, 7.837 mmol) in EtOH (100 mL) and water (10 mL) and the reaction mixture heated to reflux for 12 h. Excess EtOH was removed under reduced pressure to obtain a residue. The residue was then partitioned between water and diethyl ether. The organic layer was separated, dried over sodium sulfate, filtered and concentrated under vacuum to afford the title compound (1.2 g, 82% of yield) as a white solid. 1HNMR (CDCl3, 300 MHz): δ 5.97 (s, 2H), 4.08 (brs, 2H), 3.84 (s, 3H), 3.75 (s, 3H); MS (ESI): 188.1 [M+H]+.
