실험 절차

1 M solution (1.2 ml, 1.22 mmol) of diisobutylaluminum hydride in toluene was slowly added to a solution (10 ml) of 4-(4-nitrophenyl)benzonitrile (224 mg, 1 mmol) in toluene at room temperature, and they were stirred for 1 hour. After cooling to 0° C., methanol (0.4 ml) and water (0.4 ml) were slowly added to the obtained mixture, and they were stirred. The reaction mixture was dried over sodium sulfate. After the purification by the silica gel column chromatography (ethyl acetate/hexane), 4-(4-nitrophenyl)benzaldehyde was obtained in the form of a yellow solid (yield: 127 mg, 56%).
