3-(2-Pyridyl)-3H-1,2,3-triazolopyridine (8) upon heating in paraffin oil or polyphosphoric acid, does not give 1,8-diazacarbazole (14), but yields instead bis(2-pyridyl)amine (15) and 2-(2-pyridylamino)-3-hydroxypyridine phosphate (16), respectively; the latter compound is also obtained by treating 3-(1-oxide-2-pyridyl)-3H-1,2,3-triazolopyridine (10) with polyphosphoric acid.However, 3-(4-pyridyl)-3H-1,2,3-triazolopyridine (20) is converted by polyphosphoric acid into 3,6-diazacarbazole (23) and 4-(4-pyridylamino)-3-hydroxypyridine (24).
