Sodium Hydroxide → HCID 11823533, compound

Participants

Reaction Steps

10 ml of bis(2-methoxyethoxy)aluminium-sodium hydride was added dropwise to a solution of 2.95 g (8.7×10-2 mole) of 1-dodecyl-α,α-dimethyl-4-piperidine-acetamide in 80 ml of methylbenzene. After stirring for one hour at room temperature, the mixture was refluxed for three hours. After cooling the mixture, 50 ml of 3N sodium hydroxide was carefully added and stirring was continued for 24 hours. The resulting mixture was extracted with methylbenzene. The organic phase was washed with water, dried over magnesium sulphate and filtered and the solvents were evaporated off under reduced pressure. The product was purified using silica gel chromatography, eluting with a 4/1/0.1 (v/v/v) ethyl acetate/methanol/ammonia mixture. 1.8 g (yield: 64%) of 1-dodecyl-β,β-dimethyl-4-piperidineethanamine was obtained as an oil. The (E)-2-butenedioate was obtained from this oil in an acetone-ether mixture. M Pt=100°-120° C.
