Acetic anhydride (7.5 ml) was added to a toluene (100 ml) solution of 2-propylaniline, and the mixture was stirred at room temperature for 2 hours. Crystals thus precipitated were collected by filtration and washed with hexane. The filtrate was concentrated under reduced pressure. After hexane was added thereto, tritulation was conducted. The deposited crystals were collected by filtration and washed with hexane. By the above crystallization steps, 2-propylacetanilide (13.0 g; yield, 96%) was obtained as white crystals.
