Hydroxylamine → tert-butyl 2-(N'-hydroxycarbamimidoyl)acetate

참여 물질

반응 단계

tert-Butyl cyanoacetate (1.0 g) was dissolved in ethanol (10 mL), and aqueous hydroxyamine solution (50%, 0.5 mL) was added dropwise under ice-cooling. After stirring at room temperature for 5 hr, the mixture was diluted with ethyl acetate, and washed with brine, and the organic layer was dried over sodium sulfate. The solvent was evaporated under reduced pressure and ethyl acetate-hexane was added. The resulting precipitate was collected by filtration to give the object product (820 mg, 67%).
