Procedure

3.6 g (0.02 mole) of 5-chloro-1(beta-chloroethyl)-3-methylpyrazole was added slowly to 10 ml of concentrated sulfuric acid with swirling. Thereafter 5 ml of fuming nitric acid was then added slowly also with swirling. During the addition, the mixture became quite warm. It was allowed to stand at room temperature for 40 minutes and then poured onto ice. A white solid was formed and was filtered off, washed well with water and dried in vacuo at 56°C.
