Participants

Reaction Steps

1.7 g of sodium hydride was added to 30 ml of dry dimethylformamide, and then 7.5 g of tert-butyl 2-mercaptoethylaminoformate. Upon the end of the addition, the mixture was stirred for 1 h, and then slowly added with 2,2,2-trifluoroethyl (4-methylphenyl)sulfonate. Upon the end of the addition, the mixture was warmed to room temperature, and stirred overnight. The mixture was poured to water, extracted with diethyl ether, washed with 0.5M sodium hydroxide aqueous solution and then with saturated sodium chloride solution, dried over anhydrous sodium sulfate, distilled to remove the solvent, and subjected to a column chromatography to obtain 5.4 g of light yellow oily liquid, yield 53.8%.
