N-Iodosuccinimide → HCID 23449208, compound

Participants

Reaction Steps

N-Iodosuccinimide (3.08 g) was added under ice cooling to a solution of 2.28 g of 7-methylthioimidazo[5,1-b]thiazole in dichloromethane. The mixture was stirred at room temperature for 7 hr. Saturated brine was added to the reaction mixture, followed by separation. The organic layer was washed with a dilute aqueous sodium thiosulfate solution and saturated brine in that order, and then dried over anhydrous magnesium sulfate. The solvent was removed by distillation. The residue was purified by column chromatography on silica gel (ethyl acetate:dichloromethane=1:1) to give 3.78 g of 5-iodo-7-methylthioimidazo[5,1-b]thiazole.
