Allyl bromide → HCID 21330400, compound

Participants

Reaction Steps

To a solution of 6.0 g of 2,6-diethyl-2,3,6-trimethyl-4-piperidyl benzoate (Compound 10 - prepared using the same procedure as is described in Preparation 2) in 20 ml of dimethylformamide were added 6.0 g of allyl bromide, and the mixture was heated at 110°-115° C. for 9 hours. The mixture was then concentrated by evaporation under reduced pressure and 50 ml of benzene were added. The resulting mixture was then washed, in turn, with an aqueous solution of sodium carbonate and with water and was then dried over anhydrous sodium sulphate. After removing the solvent, the residue was distilled under reduced pressure, giving 1.6 g of Compound 36 as a colourless, viscous liquid (bp 163° C./0.004 mmHg).
