This letter describes progress towards an M4 PAM preclinical candidate inspired by an unexpected aldehyde oxidase (AO) metabolite of a novel, CNS penetrant thieno[2,3-c]pyridine core to an equipotent, non-CNS penetrant thieno[2,3-c]pyrdin-7(6H)-one core. Medicinal chemistry design efforts yielded two novel tricyclic cores that enhanced M4 PAM potency, regained CNS penetration, displayed favorable DMPK properties and afforded robust in vivo efficacy in reversing amphetamine-induced hyperlocomotion in rats.

2,6-Dihydroxy-4-methyl-3-pyridinecarbonitrile is converted via its 2,6-dichloro analog into the corresponding 2-amino-6-chloro, 2-chloro-6-amino, and 2,6-diamino derivatives.The last reacts with benzenesulfonyl chloride to yield a tris-sulfonyl derivative, the structure of which is demonstrated by X-ray analysis.
