Participants

Reaction Steps

To a stirred mixture of 10.7 parts of 2-methylimidazo[1,2-a]pyridine-7-methanol monohydrochloride and 150 parts of trichloromethane were added dropwise 9.6 parts of thionyl chloride. The resulting solution was stirred for 15 minutes at room temperature. The reaction mixture was evaporated in vacuo and the residue was stirred in 80 parts of 2-propanone. The product was filtered off, washed with 2,2'-oxybispropane and dried, yielding 11.8 parts (100%) of 7-(chloromethyl)-2-methylimidazo-[1,2-a]pyridine monohydrochloride; mp. 178.5 (intermediate 16).
