Procedure

2-chloromethyl-8-(2,6-dimethylbenzylamino)-3-methylimidazo[1,2-a]pyridine (2.4 mmol) and potassium cyanide (2.4 mmol) were added to dimethyl sulfoxide (25 ml) and stirred for 2 h. at room temperature. Methylene chloride and water were added to the reaction mixture and the organic layer was separated, dried (Na2SO4) and evaporated under reduced pressure. The residue was purified by by column chromatography on silica gel using methylene chloride:methanol (10:1) as eluent. Crystallization from acetonitrile gave 0.25 g (34%) of the title compound.
