ABSTRACT:
5-Alkyl-1-(2-pyridinyl)-1H-1,2,4-triazol-3-ols are prepared in good yield by reacting an appropriate 1-acyl-1-(2-pyridinyl)-semicarbazide with a base in the presence of a non-nucleophilic solvent. The compounds so prepared are intermediates used in the preparation of insecticides. The starting semicarbazide materials are novel compounds.
