실험 절차
An ethanol solution (51 mL) containing N-(4-acetyl-3-fluoro-5-methylphenyl)acetamide (30-2, 5.80 g, 27.7 mmol) and concentrated hydrochloric acid (20.0 mL) was heated at reflux for 15 h. The solution was added with 10% aqueous NaOH and the resultant solids were collected to give 1-(4-amino-2-chloro-6-methylphenyl)ethanone (30-3, 4.00 g, 23.9 mmol) as light yellow solids in 86% yield: 1H NMR (500 MHz, DMSO-d6) δ 6.22 (m, 2 H), 2.37 (m, 3 H), 2.22 (s, 3 H). ESI-MS: m/z 167.8 (M+H)+.
