Versuchsvorschrift

17.6 g (0.117 mole) of sodium iodide were added to a solution of 40 g (0.17 mole) of 10-(3-chloropropyl)-2-trifluoromethyl-phenothiazine in 350 ml of methyl ethyl ketone followed by the addition of first 11.8 g (0.117 mole) of triethylamine and then 17 g (0.117 mole) of 2-(4-piperidyloxy)-ethanol. The resulting solution was refluxed for 20 hours and after cooling, the precipitate was removed by vacuum filtration. The filtrate was evaporated to dryness. The oil residue was stirred with a mixture of ether and dilute hydrochloric acid and the precipitate formed was recovered by vacuum filtration and crystallized from a 95% ethanol-ether mixture to obtain 40.5 g (71% yield) of 10-[3-(4-β-hydroxyethoxypiperidino) propyl]-2-trifluoromethyl-phenothiazine hydrochloride in the form of white crystals melting at 218°-219° C on a heated microscopic stage.
