Reaction Steps

There was dissolved 149.7 g (0.7 mol) of sodium metaperiodate in 1400 ml of water, and thereto was added dropwise a solution of 164.5 g (0.7 mol) of ethyl 2-[2-(ethoxycarbonylamino)ethylthio]acetate in 125 ml of methanol under cooling with ice. After dropping the mixture was stirred for, hours under cooling with ice. The precipitate was removed by filtration and washed with water and with chloroform, successively. The filtrate was extracted with chloroform and dried over anhydrous sodium sulfate. Then the solvent was removed under reduced pressure to give 138.6 g of white solid. The solid was recrystallized from ethanol-n-hexane (1:4) to give 113.5 g of the titled compound.
