Uppfinnare: J Renz, J-P Bourgain och G Schwarz Prioritet begard [rein den 31 jail 1957 (Schweiz) Det har visat sig, att Man kan erhalla i 3-stallfling med lagre alkyltio- resp. aralkyltiogrupper substituerade fentiazinderivat med den allmanna formeln I van i R, betecknar en lagre alkyl- eller aralkylgrupp och R, betecknar en lagre alkylgrupp, genom alt man behandlar tertiara aminer med den allmanna formeln II I " CH, CH, van i R, och R, ha ovan angiven betydelse, med en svaveldihalogenid. Enligt patentet 197 686 framstalles merkapto-fentiazin-derivat med formeln I genom kondensation av merkapto-fentiaziner med 1-halogen-2-(N-alkylpiperidy1-2)-etan. Inventors: J Renz, J-P Bourgain and G Schwarz Priority requested [rein on 31 Jail 1957 (Switzerland) It has been shown that one can obtain in 3-stall flake with lower alkylthio- resp. aralkylthio groups substituted phentiazine derivatives of the general formula I van in R, denote a lower alkyl or aralkyl group and R, denotes a lower alkyl group, by treating tertiary amines of the general formula II I "CH, CH, van in R, and R According to patent 197 686, mercapto-phentiazine derivatives of the formula I are prepared by condensation of mercapto-phentiazines with 1-halo-2- (N-alkylpiperidyl-2) -ethane.

Foremal for patentet 199 324 hr ett fOrfarande for framstallning av merkapto-fentiazin-derivat med formeln I genom dekarboxylering av motsvarande 10-fentiazin-karbonsyraester-derivat. s CH, CH, 2 Foreliggande fOrfarande kan exempelvis genomforas pa sa. satt, att ett N42-(W-alkyl-piperidy1- 2)-ety1-1]-N-[merkapto-fenyll-anilin-derivat tes i ett lampligt organiskt losningsmedel, sasom bensen, toluen eller Iiknande, och under omrorning vid rumstemperatur eller forhojd temperatur sattes med en svaveldihalogenid. Efter avslutad reaktion avdrives losningsmedlet under forminskat tryck och indunstningsaterstoden upptages ef ter utrorning med vatten och alkalilut i ett lampligt, med vatten icke blandbart losningsmedel. Indunstningshterstoden av det organiska skiktet renas forst genom fraktionering i hbgvakuum och kan for ytterligare rening overforas till salt av en lamplig syra. Delta Or speciellt nodvandigt, da utengsmaterialets fenylkarnor Oro substituerade, sá att en blandning av olika isomerer kan bildas vid reaktionen, vilka isomerer skilja sig frail varandra genom substituentens stallning. Skiljning och renframstallning av komponenterna lyckas da genom fraktionerad kristallisation av deras salter. The subject of patent 199 324 is a process for the preparation of mercapto-phentiazine derivatives of the formula I by decarboxylation of the corresponding 10-phentiazine-carboxylic acid ester derivative. s CH, CH, 2 The present process can be carried out, for example, as follows. that an N42- (N-alkyl-piperidyl-2) -ethyl] -N- [mercapto-phenyl-aniline derivative is taken up in a suitable organic solvent, such as benzene, toluene or the like, and with stirring at room temperature. or elevated temperature was set with a sulfur dihalide. After completion of the reaction, the solvent is evaporated off under reduced pressure and the evaporation residue is taken up after stirring with water and alkali liquor in a suitable solvent, water-immiscible solvent. The evaporation residue of the organic layer is first purified by fractionation in a high vacuum and can be transferred to a salt of a suitable acid for further purification. Delta Or is especially necessary when the phenyl nuclei of the outer material Oro are substituted so that a mixture of different isomers can be formed in the reaction, which isomers differ from each other by the arrangement of the substituent. Separation and purification of the components then succeed by fractional crystallization of their salts.

The basic compounds prepared according to the present process are oily or crystalline at room temperature and form solid, solid salts with acids.

De enligt fOreliggande forfarande framstallda foreningarna ha terapeutiskt anvandbara, farmakodynamiska egenskaper, sasom potensiering av effekten av narkotiskt, hypnotiskt eller analgetiskt verkande farmaka och Oro darfor lampliga for behandling fore narkos. De kunna dessutom anvandas vid allergiska sjukdomar samt sasom sedativum, spasmolytikum, antiemetikum eller neuroplegikum och tjana dessutom fOr behandling av de mest olika retningstillstand. The compounds prepared according to the present method have therapeutically useful pharmacodynamic properties, such as potentiating the effect of narcotic, hypnotic or analgesic drugs and are therefore suitable for the treatment of anesthesia. They can also be used for allergic diseases as well as sedatives, antispasmodics, antiemetics or neuroplegics and also serve to treat the most different irritating conditions.
