To a solution of 10.59 g of 2-chloro-5-methoxyaniline in 50 mL of AcOH were added dropwise at 0° C. 6.8 mL of acetic anhydride. The reaction mixture was allowed to warm up to rt, stirred for 6 h and concentrated in vacuo. The crude product was purified by CC using EtOAc/heptane 1/3 to yield 13.0 g of N-(2-chloro-5-methoxy-phenyl)-acetamide as white solid.
