実験手順

To a solution of 1-(3,4-dichlorophenyl)-4,5-dihydro-1H-pyrazol-3-amine (0.62 g, 2.7 mmol) in dichlorometane (45 ml), MnO2 (1.04 g, 10.8 mmol) was added and the mixture stirred at room temperature during 4 hrs. The final mixture was filtered throught decalite and the filtered solution evaporated to dryness in vacuo. The red crude solid was crystallized in ethyl ether/petroleum ether yielding 0.46 g of 1-(3,4-dichlorophenyl)-1H-pyrazol-3-amine.
