Abstract

1,213,912. Tricyclic piperazine derivatives. SPOFA, UNITED PHARMACEUTICAL WORKS. 13 May, 1968 [15 May, 1967], No. 22548/68. Heading C2C. Novel tricyclic piperazine derivatives of formula wherein X stands for an atom of sulphur or oxygen, and R for a halogen atom, a C 1-4 alkyl group or trifluoromethyl group or a salt thereof, are prepared by condensing a chloroderivative of formula wherein X and R are as defined above, with 1- carbethoxy-piperazine so as to form the carbamate of formula wherein X and R are as defined above; reducing the carbamate with a complex hydride and when the salt is to be prepared neutralizing the base thus formed with an inorganic or organic acid to the corresponding salt. 8 - Trifluoromethyl - 10 - chloro - 10,11 - dihydro-dibenz[b,f]-thiopine is prepared by reaction of 4-trifluoromethyl-bromobenzene with 2- hydroxymethyl-thiophenol to give 2-(4-trifluoromethyl-phenylthio) benzyl alcohol, reacting this with thionyl chloride to give 2-(4-trifluoromethyl-phenylthio) benzyl chloride, reacting this with potassium cyanide to give 2-(4-trifluoromethyl-phenylthio) - acetonitrile, reacting this with potassium hydroxide to give 2-(4- trifluoromethyl-phenylthio)- acetic acid, treating this with anhydrous hydrogen fluoride to give 8-trifluoromethyl - 10,11-dihydro-dibenz-(b,f)-thiopin-10-one, reducing this with sodium borohydride to 8-trifluoromethyl-10,11 -dihydro-dibenz- [b,f]-thiopin-10-ol, and treating this with calcium chloride and anhydrous hydrogen chloride. Reference has been directed by the Comptroller to Specifications 1,093,910 and 1,123,400.
