摘要：
Substituted 6-chloropyrimido [4,5-e] [1,3,4] thiadiazine was converted to the corresponding 6-hydrazino derivative by treatment with hydrazine hydrate in DMF/Et3N. The latter was used for the syntheses of a various substituted [1,3,4] triazolo [4,3-a] pyrimido [4,5-e] [1,3,4] thiadiazines. Keywords. Thiadiazine, Dithizone, pyrimidine, trizoles, heterocyclization.
