Procedure
A 1 M Tetra-n-butylammonium fluoride/THF solution (20.0 ml) was added in an argon atmosphere at room temperature to a solution of 3.87 g of 3-methylthio-2-(trimethylsilyl)imidazo[5,1-b]-thiazole in 70 ml of dry THF. The mixture was stirred at the same temperature for 15 min. Semi-saturated brine was added to the reaction mixture. Ethyl acetate was then added thereto, followed by washing with semi-saturated brine. The organic layer was dried over anhydrous magnesium sulfate. The solvent was removed by distillation. The residue was purified by column chromatography on silica gel (ethyl acetate) to give 2.62 g of 3-methylthioimidazo[5,1-b]thiazole.
