Procedure

5.9 g (0.022 mol) of 2-bromo-4'-methoxy-3',5'-dimethylpropiophenone are dissolved in 30 ml of ethanol, 4.2 g (0.022 mol) of 4-(4-methylbenzyl)-piperidine and then 2.12 g (0.02 mol) of sodium carbonate are added and the mixture is heated under reflux for 2 hours. It is left to cool, the inorganic precipitate is filtered off and the filtrate is evaporated. The residual oil is purified by chromatography on silica using acetone as the eluant. This gives 8 g of a product, which is used as such.
