Reaction Steps

A mixture of N-acetylglycine (5.00 g, 42.7 mmol), 4-trifluoromethoxybenzaldehyde (9.30 g, 47.0 mmol), sodium acetate (4.55 g, 55.5 mmol), and acetic anhydride (20 mL, 213 mmol) was stirred at 120° C. for 1 hour, and then was cooled to room temperature. After further ice-cooling, the precipitated yellow solid was suspended in water. The insoluble substance was collected by filtration, washed with water, and dried by heating under reduced pressure to give 10.7 g of the title compound (yellowish brown crystal, yield: 92%).
