Triazolo[4,5-d]pyrimidines. X. Halogen-metal exchange reaction of 7-halo-3-phenyl-3H-1,2,3-triazolo[4,5-d)pyrimidines with butyllithium

The amino group at the 7-position on the 3H-1,2,3-triazolo[4,5-d]pyrimidine ring was converted into halogen atoms by treatment with isopentyl nitrite in halomethanes, in satisfactory yields. The halogen-metal exchange reaction between 7-iodo-3-phenyl-3H-1
