Rapid analogue synthesis of trisubstituted triazolo[4,3-b]pyridazines

A rapid analogue synthesis of biologically active 3,6,7-trisubstituted 1,2,4-triazolo[4,3-b]pyridazines was devised to give easy and selective variation of the three substituents through combinations of silicon-directed anion formation, palladium-catalysed couplings and S(N)Ar displacements.
