Ethanol → HCID 136005283, compound

Participants

Reaction Steps

Allyloxyamine hydrochloride (0.17 g) and then a solution of sodium hydroxide (0.06 g) in water (1 ml) were added to a stirred mixture of 3-hydroxy-2-propionyl-5-(3-bromo-2,4,6-trimethylphenyl)cyclohex-2-en-1-one (0.50 g, 1.37 mmole) and 95% ethanol. The progress of the reaction was monitored using thin layer chromatography on silica gel (eluant dichloromethane). On completion of the reaction the ethanol was removed by evaporation under reduced pressure and the residue was extracted with dichloromethane. The organic extract was washed with aqueous 5% hydrochloric acid and then with water and dried over anhydrous magnesium sulfate. The solvent was removed by evaporation under reduced pressure to give the product, 2-[1-(allyloxyimino)propyl]-3-hydroxy-5-(3-bromo-2,4,6-trimethylphenyl)cyclohex-2-en-1-one (0.33 g, 57.4%) as an oil.
