Abstract
4-Chloromethylpyrazoles are shown to react readily with amides, carbamates, ureas and azoles under neutral conditions giving the corresponding N-monoalkylated derivatives with moderate yields. Alkylation of alcohols and thiols occurs under the same conditions. The procedure described may provide a convenient and easy method for the introduction of a 4-pyrazolylmethyl group into molecules containing functional groups with weak nucleophilic character.
