実験手順
A mixture of 1.0 g. of 6-(phenyl)-1,2,4-triazolo[4,3-a]pyrimidine and 10 ml. of 97% formic acid is refluxed for 5 hours and the excess formic acid is removed under reduced pressure. The solid residue is collected, washed with hexane and recrystallized from glacial acetic acid to give the product as crystals, m.p. 164°-167° C.
