This Letter details our efforts to discover structurally unique M4 PAMs containing 5,6-heteroaryl ring systems. In an attempt to improve the DMPK profiles of the 2,3-dimethyl-2H-indazole-5-carboxamide and 1-methyl-1H-benzo[d][1,2,3]triazole-6-carboxamide cores, we investigated a plethora of core replacements. This exercise identified a novel 2,3-dimethylimidazo[1,2-a]pyrazine-6-carboxamide core that provided improved M4 PAM activity and CNS penetration.

Hexahydromidazo[1,2-c]pyrimidines 6 were prepared by the reaction of tosylpyrimidines 2 with bromoacetamides 3 in one step. The stereoselectivity of the reaction has been confirmed by X-ray analysis. Imidazo[1,2- a]pyrimidines 5 were obtained on heating h
