Reaction Steps

Into a 100-mL 3-necked round-bottom flask purged and maintained with an inert atmosphere of nitrogen, was placed a solution of 1-(4-aminophenyl)ethanone (3.1 g, 22.96 mmol, 1.00 equiv) in dichloromethane (30 mL), triethylamine (4.64 g, 45.94 mmol, 2.00 equiv). This was followed by the addition of acetyl chloride (1.79 g, 22.95 mmol, 1.00 equiv) dropwise with stirring at 0° C. The resulting solution was stirred for 30 min at 0° C. The reaction was then quenched by the addition of 2 mL of water. The resulting mixture was washed with 3×50 mL of saturated aqueous sodium chloride. The mixture was dried over anhydrous sodium sulfate and concentrated under vacuum to give 3.0 g (74%) of N-(4-acetylphenyl)acetamide as a white solid.
