Acetyl chloride (5.6 ml) and triethylamine (12.5 ml) were added dropwise to a chloroform (50 ml) solution of 2-propylaniline (10.5 g) in this order under ice-cooling. The reaction solution was stirred at room temperature for 3 hours. The solution was concentrated under reduced pressure, and the thus-obtained solid was washed with water and collected by filtration. The resulting residue was recrystallized from ethanol-water to obtain 2-propylacetanilide (11.85 g; yield, 86%) as white crystals.
