Reaction Steps

A mixture of 4-amino-benzoic acid ethyl ester (4.5 g, 27 mmol) and 4-bromo-benzaldehyde (5.0 g, 27 mmol) in ethanol (150 mL) was prepared. The reaction mixture was heated to reflux for 2 h. Then the reaction mixture cooled to room temperature. The solvent was removed in vacuo and the residue was washed with ether to afford 4-{[1-(4-bromo-phenyl)-methylidene]-amino}-benzoic acid ethyl ester (6.3 g, 70%) as a white solid: LC/MS m/e calcd for C16H14BrNO2 M+: 332.2, observed: 332.2, 334.2.
