Reaction Steps

A solution of ruthenium(III)chloride hydrate (440 mg, 2.12 mmol, 0.003 equiv) and sodium metaperiodate (132.2 g, 0.62 mol) in water (1.5 l) is stirred for 45 min and added at a temperature of 20-25° C. over a period of 35 min to a suspension of the crude product of Step b (140 g) in a mixture of acetonitrile (0.6 l) and saturated aqueous solution of disodium hydrogen phosphate (0.3 l). During the addition the pH of the suspension is kept between 6.9 and 7.3 by the continuous addition of additional saturated aqueous solution of disodium hydrogen phosphate (1.0 l). After the addition has ended the reaction mixture is stirred for 1 hour at 20° C., the pH is adjusted to 6.4 with 1 M hydrochloric acid and then stirring is continued for a further hour. The solid is collected by filtration, washed with water (3×100 ml) and lastly stirred for 2 hours with water (1.5 l). The crystals are isolated by filtration, washed with water (3×0.1 l) and dried at 50° C.
