実験手順
3 g (0.026 mol) of butane-2,3-dione mono-(O-methyl oxime) are heated at 60° C. in 20 ml of ethanol with 2.6 g (0.052 mol) of hydrazine hydrate for 1 hour. The reaction mixture is poured onto water and extracted with diethyl ether, the organic phase is dried over sodium sulphate and the solvent is distilled off in vacuo. The residue is stirred with petroleum ether and the crystals are filtered off. 1 g (29.7% of theory) of 3-hydrazono-butan-2-one O-methyl oxime is obtained.
