To a solution of methyl 4-aminobenzoate (7.94 g, 52.5 mmol) in ethanol (100 mL) was added benzyl 3-formylbenzoate in ethanol (50 mL) and the resulting mixture was stirred at room temperature for 2 h. The white solid precipitated was collected by filtration and washed with ethanol, dried in vacuo (50° C.) to give 15.6 g of (E)-benzyl 3-((4-(methoxycarbonyl)phenylimino)methyl)benzoate as a white solid.
