Participants

Reaction Steps

3-Amino-1-(p-chlorophenyl)-2-pyrazoline (5 g) was added to acetic anhydride (4.0 ml) at room temperature. On stirring with a glass rod the mixture became warm and afforded a dark red liquid. The mixture was taken up in dichloromethane (100 ml) washed (water, 100 ml; saturated sodium bicarbonate, 100 ml; water, 100 ml), dried over sodium sulphate and the solvent removed in vacuo to afford the title compound (m.p. 171°-173°).
