Reaction Steps

To a solution of ethyl-4-aminobenzoate (5.0 g, 30.3 mmol) in ethanol was added 2-nitrobenzaldehyde (5.03, 33.3 mmol) at room temperature. The reaction mixture was stirred at reflux for 3 h LC-MS showed ester was consumed nearly. The reaction mixture was concentrated in vacuo. The residue was washed by diethyl ether to give ethyl 4-(2-nitrobenzylideneamino)benzoate as yellow solid (7.8 g, yield 86.4%). LC/MS m/e obsd. (ESI+) [(M+H)+] 299.2.
