Procedure
4.10 g of 5-(2-methanesulfonyloxyethyl)-3-p-methoxyphenyloxazolidin-2-one [m.p. 61°-64°; obtainable by reaction of 3,4-epoxy-1-butanol with N-benzyl-p-methoxyaniline to give 1-(N-benzyl-p-methoxyanilino)butane-2,4-diol (resin), hydrogenolysis to give 1-p-methoxyanilinobutane-2,4-diol (resin), reaction with diethyl carbonate to give 5-(2-hydroxyethyl)-3-p-methoxyphenyloxazolidin-2-one (m.p. 77°-78°) and reaction with CH3SO2Cl] are boiled together with 3.13 g of 4-hydroxy-4-(3,4-methylenedioxyphenyl)piperidine ("M"), 2.16 g of potassium iodide and 1.8 g of potassium carbonate in 100 ml of acetonitrile for 16 hours, the mixture is cooled, worked up as usual, to give 5-[2-(4-hydroxy-4-(3,4-methylenedioxyphenyl)piperidino)ethyl]-3-p-methoxyphenyloxazolidin-2-one, m.p. 128°-130°.
