Abstract

Alkylation of 3-alkyl-6-methyl-5,7-dioxo-4,5,6,7-tetrahydro-1,2,3-triazolo[4,5-<i>d</i>]pyrimidines <i>I</i> with alkyl halides in dimethylformamide in the presence of potassium carbonate, or by analogous alkylation of sodium salts of compounds <i>I</i> afforded the respective 4-alkyl derivatives <i>III</i> but not 5-alkyloxy-3-alkyl-6-methyl-7-oxo-6,7-dihydro-1,2,3-triazolo[4,5-<i>d</i>]pyrimidines <i>IV</i> or isomeric 1,3-dialkyl-6-methyl-5,7-dioxo-4,5,6,7-tetrahydro-1,2,3-triazolo[4,5-<i>d</i>]pyrimidinium halides <i>II</i>.
