実験手順
This material was prepared by reduction of 2-benzylthio-6,7-dichloro-5-methyl-1,2,4-triazolo[1,5-a]pyrimidine with zinc-copper couple following the general procedure described in Example 21. The desired product was isolated in 88% yield as a solid, m.p. 160°-161° C. IR and 1H NMR spectra were in agreement with the assigned structure.
