To a stirred solution of N-(2-mercapto-2-methylpropionyl)-L-cysteine (11.2 g) in dimethylformamide(50 ml), trityl chloride(16.7 g) was added slowly. The reaction mixture was stirred for 2 hours at room temperature, poured into water and extracted with ethyl acetate. The organic layer was washed with water and saturated sodium chloride solution, dried over anhydrous magnesium sulfate and concentrated in vacuo. The oily residue was purified by a silica gel column chromatography to give 14.2 g(60%) of the titled compound.
