The present invention is directed to compounds of formula (I) which are M1 receptor positive allosteric modulators and that are useful in the treatment of diseases in which the M1 receptor is involved, such as Alzheimer's disease, schizophrenia, pain or sleep disorders. The invention is also directed to pharmaceutical compositions comprising the compounds, and to the use of the compounds and compositions in the treatment of diseases mediated by the M1 receptor.

A copper(I)-catalyzed interrupted dominoreaction of 2-azido sulfoximines with 1-iodoalkynes affords fused triazolyl-containing benzothiadiazine-1-oxides in good to excellent yields. The substrate scope is broad and the functional group tolerance high. Mechanistic studies suggest a reaction pathway via copper π-complexes and a consecutive oxidative coupling of a relevant iodinated triazole as intermediate
