Procedure

N-(3-Methoxy-phenyl)-acetamide (17.7 g, 107 mmol) in methylene chloride was cooled to zero degrees C, and acetyl chloride (19.0 ml, 268 mmol) was slowly added, followed by aluminum chloride (35.7 g, 268 mmol) in small portions over 15 min. The reaction mixture was stirred 15 minutes at zero degrees, then allowed to warm to room temperature with stirring. The reaction mixture was poured into ice, stirred 35 minutes, and filtered. The solid was washed with water. The filtrate was extracted with EtOAc and solvent was removed under reduced pressure. The combined solids gave N-(4-Acetyl-3-methoxy-phenyl)-acetamide (16.5 g., 74% ) as a solid.
