l)- triazolo[4,3-b]pyridazine (9). Dehalogenation of 9, followed by debenzoylation, gave the formycin congener 8-amino-3-beta-D-ribofuranosyl-1,2,4- triazolo[4,3-b]pyridazine (5). Similar condensation of 5-amino-4-chloro-3-hydrazinopyridazine (13) with 6 and dehalogenation of the cyclized product (16), followed by debenzoylation, gave the isomeric 7-amino-3-beta-D-ribofuranosyl-1,2,4- triazolo[4,3-b]pyridazine
