الإجراء التجريبي

36.7 g of 2,6-diethyl-2,3,6-trimethylpiperidine and 30 g of allyl bromide are stirred for 7 days with heating at about 75° C. The reaction mixture is made alkaline by addition of 200 ml of 2 n sodium hydroxide and is extracted with ether. The ethereal solution is dried over K2CO3 and evaporated. The residue is purified by fractional distillation yielding 1-allyl-2,6-diethyl-2,3,6-trimethylpiperidine (Compound No. 4) which distills at 132°-135° C./16 mm Hg.
