Versuchsvorschrift

To a stirred and refluxing mixture of 5 parts of 4-chloro-N-(4-chlorophenyl)-N-(4-piperidinyl)benzeneacetamide, 5 parts of sodium carbonate, 0.4 parts of potassium iodide and 200 parts of butanol is added 4.7 parts of 1-iodopropane and the whole is stirred and refluxed for 22 hours. Then a second portion of 4.5 parts of 1-iodopropane is added and stirring and refluxing is continued for 27 h. 30. The reaction mixture is cooled, filtered and the filtrate is evaporated. The semi-solid residue is dissolved in methylbenzene. The solution is filtered from some impurities and the filtrate is evaporated again. The residue is crystallized from 1,1'-oxybisethane at -10° C., yielding 0.9 parts of 4-chloro-N-(4-chlorophenyl)-N-(1-propyl-4-piperidinyl)benzeneacetamide; mp. 118.6° C.
