Versuchsvorschrift

A mixture of 42.4 g (80 mmol) of N,N-dioctadecylhydroxylamine, 13 ml (150 mmol) of allyl bromide and 17.0 g (160 mmol) of sodium carbonate in 450 ml of ethanol is heated under reflux at approximately 80° to 85° C. The reaction is considered complete after 14 hours upon complete disappearance of the N,N-dioctadecylhydroxylamine as indicated by TLC analysis (silica gel, chloroform solvent). The reaction mixture is concentrated under reduced pressure and the resultant residue is triturated with 500 ml of chloroform. The insoluble salts are removed by filtration and the filtrate concentrated. The resultant residue is purified by flash chromatography (silica gel, chloroform solvent) to give 16.6 g (36% yield) of the title compound as a white solid melting at 60°-62° C.
