Abstract
Reactions of hydroxyphenyl substituted 1,2,4-triazoles with various electrophylic reagents were studied. Despite of the presence of several nucleophilic centers in the molecule, the reactions were shown to proceed regioselectively, with the formation of N-substituted 3-(2-hydroxyphenyl)-1,2,4-triazoles. As a result of the reactions of alkylation, tosylation, sulfoamination and aminomethylation by Mannich reaction earlier unknown potential biologically active N-derivatives of 1,2,4-triazole were obtained.
