Chlorotrimethylsilane → HCID 23449325, compound

Participants

Reaction Steps

A 1.6 N n-butyllithium/n-hexane solution (16.7 ml) was added in an argon atmosphere at −50° C. to a solution of 3.17 g of imidazo[5,1-b]thiazole in 120 ml of dry THF. The mixture was stirred at the same temperature for 30 min. Trimethylsilyl chloride (3.54 ml) was added thereto, and the mixture was stirred for 20 min. A 1.6 N n-butyllithium/n-hexane solution (8.0 ml) was added thereto, and the mixture was stirred for 20 min. A saturated aqueous ammonium chloride solution was added to the reaction mixture. Ethyl acetate was then added thereto, followed by washing with water and saturated brine in that order. 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 4.53 g of 2-(trimethylsilyl)imidazo[5,1-b]thiazole.
