The reaction of Schiff bases prepared from 1‐ and 2‐substituted‐5‐amino‐1,2,4‐triazoles with phenoxyacetyl chlorides in the presence of triethylamine and a mixture of phosphorus oxychloride and dichloroacetic acid in dimethylformamide to yield β‐lactam 4 , a dihydro‐1,2,4‐triazolo[4,3‐a]pyrimidine‐5(1 H )‐one 5, a 1,2,4‐triazolo[1,5‐ a ]pyrimidin‐5(3 H )‐one 9 and the corresponding 1,2,4‐triazolo[4,3‐ a ]pyrimidine‐5(1 H )‐one 10 derivatives was studied.
