Generation of triazolopyrimidine N-Ylides and Their Ring Transformation Reactions

Triazolopyrimidine (1) has been alkylated at the N(3)-position by treatment with alkyl halides in refluxing dry acetone.The ylides (3) were generated in situ from the iminium salts (2) and 1 equiv. of triethylamine.Thermolysis of the ylides
