Halogenation of pyrazoles using N-halosuccinimides in CCl4 and in water

Reaction of pyrazoles with N-halosuccinimides (NXS, X=Br, Cl) in either CCl4 or water gave 4-halopyrazoles in excellent yields. The reaction was carried out under mild conditions and did not require any catalysts or special precautions. The reaction provides an efficient method for 4-C halogenation of pyrazoles.
