Abstract: 2-(Phenylthiopropyl)-5-aryl-1,2,3,4-tetrahydro-.gamma.-carboline tranquilizing agents and the preparation thereof from 5-aryl-1,2,3,4-tetrahydro-.gamma.-carbolines.

Abstract: Compounds of the formula ##STR1## and pharmaceutically acceptable salts thereof, wherein X and Y are independently H, F, Cl, Br, alkyl having up to four carbons, or alkoxy having up to four carbons, but X and Y are not both H, and Z is a secondary or tertiary amino group, are useful as analgesics and tranquillizing agents for mammals.

Abstract: Certain indole derivatives, and especially certain 1,2,3,4-tetrahydrocarbazoles, 1,2,3,4-tetrahydro-.gamma.-carbolines and 1,2,3,4-tetrahydropyrrolo-[3,4-b]indoles are prepared by reacting the appropriate phenylhydrazine salt and ketone in the presence of a weakly basic solvent such as pyridine, quinoline, N,N-dimethylaniline, picoline or lutidine at a temperature in the range of about 50.degree. to 180.degree.
