Reaction Steps

To a solution of 6-amino-2-methylnicotinonitrile (960 mg) in ethanol (34 ml) was added a 40% aqueous chloroacetaldehyde solution (2.36 ml) at 60° C. The reaction mixture was refluxed for 8 hours. The resulting precipitates were collected by filtration to obtain 5-methylimidazo[1,2-a]pyridine-6-carbonitrile hydrochloride (580 mg) as a white solid.
