Participants

Reaction Steps

To a solution of 5-[3-(hydroxy)propylthio]imidazo[1,2-a]pyridine (1.00 g, 4.80 mmoles) and triethylamine (0.80 ml, 5.74 mmoles) in methylene chloride (25 ml) was added benzoyl chloride (1.10 ml, 11.6 mmoles) with stirring at room temperature and the mixture was further stirred at room temperature for 30 minutes. The reaction mixture was washed with an aqueous 1N sodium hydroxide solution and dried. After the solvent was distilled off, the residue was purified by column chromatography [eluent: hexane/acetone (1:1)] to obtain 1.32 g of the desired product (88.1%, white solid).
