Participants

Reaction Steps

Tri-n-butylstannyl chloride (1.21 ml) and 9.47 ml of a 1.0 N lithiumbis(trimethylsilyl)amide/THF solution were added to a solution of 1.11 g of 7-[3-(4-nitrobenzyloxycarbonyl)aminopropyl]thioimidazo[5,1-b]thiazole in 28 ml of THF at −45° C. under an argon atmosphere, and the mixture was stirred for one hr. An aqueous ammonium chloride solution was added to the reaction solution, and the mixture was extracted with ethyl acetate, followed by washing with brine. The organic layer was dried over anhydrous magnesium sulfate. The solvent was then removed by distillation, and the residue was purified by column chromatography on silica gel (hexane:ethyl acetate=1:1) to prepare 1.24 g of the title compound.
