실험 절차

The 3-[(2E)-3-(dimethylamino)prop-2-enoyl]benzonitrile (0.600 g, 0.00300 mol) was dissolved in ethanol (20.0 mL, 0.342 mol) and hydrazine (0.56 mL, 0.018 mol) under an atmosphere of nitrogen was stirred at room temperature for 1.5 h. The reaction was concentrated in vacuo to give a dark product which was purified by FCC on silica gel, eluting with ethyl acetate-hexane 1:1 to give 3-(1H-pyrazol-3-yl)benzonitrile as an oil (0.430 g, 84%), LC/MS (M+H)+: 170.
