derivatives at the action of thionyl chloride on hydroxymethyl derivatives of 1-alkylpyrazoles. Compound II was found to be the reaction product. They believed that in 1-alkylpyrazoles series hydroxymethyl moiety in the position 4 is extremely labile and behaves as 1-oxymethyl group, which readily departed at the action of acidic agents [2]. Due to this compound I transforms smoothly into bis(1,3,5trimet
