To a stirred solution of ethyl 2-(2-hydroxypropylamino)-2-oxo-acetate (10.7 g, 61.07 mmol) in DCM (100.0 mL), is added Dess Martin periodinane (25.9 g, 61.07 mmol) at 0° C. The reaction mixture is stirred at room temperature for 2 hours, diluted with water (100 mL) at 0° C., and extracted with DCM (2×100 mL). The combined organic layer is washed with water (2×50 mL) and saturated brine (50 mL), dried over Na2SO4, and evaporated under reduced pressure. The crude material is purified by silica gel chromatography, eluting with hexane:ethyl acetate (1:1) to give the title compound as a light yellow oil (9.2 g, 87.03%). ESI/MS m/z 174.1 (M+H)+.
