Procedure

Using the method of Example 19, 2-ethylthio-4-hydrazino-6-phenylpyrimidine was reacted with triethyl orthoacetate to provide 5-ethylthio-3-methyl-7-phenyl-1,2,4-triazolo[4,3-c]pyrimidine which was recrystallized from a 50/50 mixture of ethyl acetate/cyclohexanes to provide white crystals of 5-ethylthio-3-methyl-7-phenyl-1,2,4-triazolo[4,3-c]pyrimidine, m.p. 219.5°-220° C.
