Reaction Steps

A mixture of 2.30 g (0.02 mol) of 3-(hydroxymethyl)piperidine, 5.5 ml (0.04 mol) of triethylamine and 4.90 g (0.02 mol) of 2-(3,4-dimethoxy-phenyl)-ethyl bromide is refluxed for 2 hours. After cooling, the reaction mixture is dissolved in a mixture of 2 molar sodium hydroxide solution and methylene chloride. The organic phase is washed with water, separated off, dried over magnesium sulphate, evaporated down in vacuo and purified over 300 g of aluminium oxide (neutral, activity II-III) with methylene chloride and then with increasing amounts of ethanol (up to 2%). Yield: 4.4 g (78.7% of theory), Melting point: 87.5°-89° C.
