This material was prepared by heating 2-benzylthio-5-(2,2,2-trifluoroethoxy)-1,2,4-triazolo[1,5-a]-pyrimidine in boiling ethanol. The hot mixture was filtered and the filtrate was concentrated. The crude product was recrystallized from isopropanol to yield the desired product as a solid, m.p. 115°-117° C. IR and 1H NMR spectra were in agreement with the assigned structure.
