Participants

Reaction Steps

To a solution of 46.45 g (0.4 mol) of methyl acetoacetate in 200 ml of diethylether, 30.4 g (0.44 mol) of sodium nitrite was added and the mixture was cooled in an ice bath and treated dropwise with 40 ml (0.48 mol) of a concentrated hydrochloric acid. After stirring for 1 hour at room temperature, 200 ml of water was added and the mixture was extracted three times with 200 ml of diethylether. After washing with water and a saturated aqueous sodium chloride followed by drying over with anhydrous magnesium sulfate, the solvent was distilled off to obtain 50.09 g (yield: 86%) of a crude methyl 2-hydroxyiminoacetoacetate as a pale yellow oil. (2) Synthesis of methyl 2-benzyloxyiminoacetoacetate
