The known beta -hydroxyethyl-(1,2,4-triazole) derivatives of the formula <IMAGE> (I) in which R1 represents alkyl, halogenoalkyl, alkenyl, alkinyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted aryl, optionally substituted aralkyl, optionally substituted aralkenyl or an optionally substituted heterocyclic radical and R2 represents hydrogen, alkyl, halogenoalkyl, alkenyl, alkinyl, optionally substituted cycloalkyl, optionally substituted cycloalkenyl, optionally substituted aryl, optionally substituted aralkyl, optionally substituted aralkenyl or an optionally substituted heterocyclic radical, are prepared by a new process, which comprises stirring a beta -hydroxyethyl-(1,3,4-triazole) derivative of the formula <IMAGE> (II) in which R1 and R2 have the abovementional meanings, in the presence of a base and in the presence of an aprotic, dipolar diluent.
