2-chloromethyl-8-(2,6-dimethylbenzylamino)-3-methylimidazo[1,2-a]pyridine (0.2 g, 0.64 mmol) and sodium methanethiolate (0.1 g, 1.3 mmol) were added to acetonitrile(10 ml) and stirred for 4 h. at room temperature. The solvent was evaporated under reduced pressure and to the residue were added methylene chloride and water. The organic layer was separated, dried (Na2SO4) and evaporated under reduced pressure. Purification of the residue by column chromatography on silica gel using diethyl ether:petroleum ether (1:2) as eluent and crystallization from diethyl ether:petroleum ether (1:2) gave 0.05 g (24%) of the desired product.
