Preparation 12 A mixture of 9.95 g. (0.07 mole) of 4-acetylaminopiperidine, 12.7 g. (0.095 mole) of alpha-phenylpropionaldehyde and a trace of p-toluenesulfonic acid in 150 ml. of toluene was refluxed under a Dean-Stark trap for about one and a quarter hours, during which time 1.1 ml. of water was collected. The solution was then taken to dryness in vacuo, the residual traces of water were azeotroped by distillation with ethanol, and the residue was dissolved in 200 ml. of ethanol and the mixture reduced with hydrogen over platinum oxide under an initial hydrogen pressure of 42 psig. When reduction was complete, the catalyst was removed by filtration, the filtrate was taken to dryness, and the residue was partitioned between toluene/ethyl acetate and water. The layers were separated, and the organic extracts were washed with dilute hydrochloric acid. The combined aqueous phase was rendered strongly basic with aqueous potassium hydroxide and extracted two times with toluene. The toluene extracts, on washing with brine, drying over anhydrous sodium sulphate and evaporation to dryness, afforded 16.3 g. of an oil which was crystallized from toluene/hexane to give 12.95 g. of 1-(2-phenylpropyl)-4-acetylaminopiperidine, m.p. 102-103 C.

EXAMPLE 12 A mixture of 0.042 mole of 2,6-dibromopyridine, 0.056 mole of anhydrous potassium carbonate and 0.052 mole of 4-acetamidopiperidine in 75 ml of sulfolane is heated to 150 C. with stirring for 20 hours, then the sulfolane is concentrated to 1/5th of its volume, the reaction mixture is poured in 100 ml of water and extracted with diethyl ether (4*150 ml). The organic phase is washed with water, dried over anhydrous sodium sulfate, concentrated to dryness and the residue is crystallized in 40 ml of ethyl acetate. The 4-acetamido-1-(6-bromo-2-pyridyl)piperidine is thus obtained; m.p. 158 to 160 C. Yield: 56% of the theoretical., 5810-56-0
