Procedure
In step (3) of Reaction Scheme VI, a 4-chloro-1H-imidazo[4,5-c]pyridine of Formula XLII is reacted with sodium phenoxide to provide a 4-phenoxy-1H-imidazo[4,5-c]pyridine of Formula XXXII-4. Phenol is reacted with sodium hydride in a suitable solvent such as diglyme (bis(2-methoxyethyl) ether) to form the phenoxide. The phenoxide is then reacted at an elevated temperature with a compound of Formula XLII. The product can be isolated from the reaction mixture using conventional methods.
