Reaction Steps

To a suspension of tetrahydro-pyran-4-carbaldehyde (36.9 g, 259 mmol) and hydroxylamine (27.2 g, 388 mmol) in ethanol (246 mL) and water (246 mL) was added sodium acetate (42.9 g, 517 mmol) and the resulting mixture heated at 90° C. overnight. After cooling to room temperature the resulting mixture was then evaporated and extracted with diethylether and water. The organic extract was then washed with water, brine, dried over sodium sulfate and evaporated. Purification by chromatography (silica, heptane:ethyl acetate=1:1) afforded the title compound (16.8 g, 50%) which was obtained as a yellow liquid. MS: m/e=129.1 [M+H]+.
