실험 절차

A solution of 3-chloro-2-methylaniline (9.0 g, 63.56 mmol) in EtOH (75 mL) was treated with acetic anhydride (7.2 mL, 76.31 mmol) and the resulting mixture was stirred at rt for 3 h. Concentration was followed by crystallization from hexanes/EtOAc (1:3) to afford 11.2 g of the title compound: 1H NMR (300 MHz, DMSO-d6) δ 9.52 (s, 1H), 7.30-7.23 (m, 2H), 7.17-7.13 (m, 1H), 2.18 (s, 3H), 2.06 (s, 3H).
