To a solution of 3-chloro-5-nitrobenzaldehyde (371 mg, 0.1 mmol) in ethanol (6 mL) was added methyl 4-aminobenzoate (302 mg, 2.0 mmol). After a while, solids precipitated from the resulting clear yellow solution. The precipitated solid was filtered and 346 mg of (E)-methyl 4-(3-chloro-5-nitrobenzylideneamino)benzoate as a yellow solid was obtained. Yield=54%.
