Abstract

General, high-yielding MAOS protocols for the expedient synthesis of functionalized 3, 6- disubstituted-[1, 2, 4] triazolo [4, 3-b] pyridazines are described amenable to an iterative analog library synthesis strategy for the lead optimization of an M1 antagonist screening hit. Optimized compounds proved to be highly selective M1 antagonists.
