Reaction Steps

The title compound is synthesized as described for 7-[2-(6-{4-cyano-phen-1-yl}-3H-imidazo[4,5-b]pyridin-2-yl)-ethyl]-azepan-2-thione (compound A2) from 125 mg of N-methyl-4-{2-[2-(7-oxo-azepan-2-yl)-ethyl]-3H-imidazo[4,5-b]pyridin-6-yl}-N-(tetrahydro-furan-2-ylmethyl)-benzenesulfonamide (compound B10) and 104 mg of Lawesson's reagent. Purification by chromatography on flash silica gel (eluent gradient: dichloromethane/0-10 vol. % ethanol) affords 123 mg of the title compound as a waxy solid. ESI-MS: 528.9 (MH+). TLC: Rf=0.43 (dichloromethane/ethanol 10:1 parts by volume).
