A mixture of N-[4-(2-cyclopropylethoxy)benzoyl]glycine (184 mg, 0.699 mmol) prepared in Example 9 (9b), 4-cyclopropylbenzaldehyde (113 mg, 0.769 mmol) prepared in Example 5, sodium acetate (75 mg, 0.909 mmol), and acetic anhydride (660 μL, 6.99 mmol) was stirred at 120° C. for 30 minutes and was then allowed to cool to room temperature. Hexane (2 mL) and water (4 mL) were added to the resulting solidified product which was washed by ultrasonic vibration. The precipitate was collected by filtration, washed with water and hexane, and dried by heating under reduced pressure to give 196 mg of the title compound (white powder, yield: 74%).
