Procedure

11.28 g of the (imidazo[1,2-a]pyridin-6-yl)methanol prepared in the Preparative Example 6 was dissolved in 170 ml of chloroform, followed by the dropwise addition of 11.1 ml of thionyl chloride at room temperature under stirring. After one hour, the solvent was distilled off. Thus, crude 6-chloromethylimidazo-[1,2-a]pyridine hydrochloride was obtained as a light-brown powder.
