## Abstract Some new 1,2,3βtriazolo[4,5β__d__]β1,2,4βtriazolo[4,3βb]pyridazines were prepared starting from the corresponding 1,2,3βtriazolo[4,5β__d__]pyridazines __via__ the formation of the 1,2,4βtriazole ring, by condensation of an appropriate monocarbon fragment with the 4βhydrazino substituent
With sodium borohydride in tetrahydrofuran/ethanol (5 : 1). the product ( I ) gives a 75 yield of a compound, m.p. 233 "C, that is identical with the recently prepared 2-(diphenylmethyl)imidaz0le[~1. When product ( I ) is boiled for 2 h in tetrahydrofuran/water (2: I ) it affords 2-(hydroxy-dipheny
