Versuchsvorschrift

To a solution of N-Boc-N-methyl-1-amino-2,3-propandiol (20g, 0.097 mol) in water (100 ml) was added KIO4 (24.68g, 0.108 mol). The reaction mixture was stirred for 2.5 hr under an atmosphere of nitrogen and then filtered. The filtrate was extracted with chloroform (5×50 ml). The resulting chloroform extracts are dried over MgSO4, filtered, and evaporated to dryness. The title compound 13.26g (79%) was isolated as a clear oil (bp 76-80° C. at 0.5 mm Hg).
