A solution of 726.22 mmol of bis(3-methoxypropyl) sulphite in 330 ml of tetrachloromethane, 330 ml of acetonitrile and 830 ml of water is cooled to 15° C., and 18.16 mmol of ruthenium(III) chloride hydrate are added. 1089.34 mmol of sodium periodate are added in small portions, and the reaction mixture is stirred at room temperature overnight. It is diluted with ethyl acetate, and the organic phase is separated off, dried with sodium sulphate and evaporated. The crude title compound is obtained as a beige liquid from the residue and is employed without further purification in the next stage.
