Reaction Steps

Acetic anhydride (4.3 mL, 45.45 mmol) was added to a mixture of 4-ethylaniline (5.0 g, 41.32 mmol) and pyridine (20 mL) and the resulting mixture was stirred at room temperature overnight. The reaction mixture was partitioned between dichloromethane and an aqueous solution of hydrochloric acid. The organic layer was separated, dried over anhydrous sodium sulfate, filtered and evaporated under reduced pressure to give 6.857 g of N-(4-ethyl-phenyl)-acetamide as a brown solid without further purifications.
