실험 절차

To a solution of 2-hydrazino-benzoic acid mono hydrochloric acid salt (13.66 g, 72.42 mmol) dissolved in water (580 mL) and ethanol (125 mL) was added a solution of benzaldehyde (7.35 mL, 72.42 mmol) in ethanol (20 mL) dropwise at room temperature. The reaction mixture was stirred at room temperature for an additional 3 hours. The resulting solid was collected by filtration and dried in a vacuum oven to provide 12.0 g (69%) of 2-(N′-benzylidene-hydrazino)-benzoic acid as a yellow solid.
