Abstract
Process for the production of 5-phenyl-1,3,4,4a, 5,9b-hexahydro-2H-indene [1,2-c] pyridines, of the general formula **(See formula)** wherein either R2 and R3 signify hydrogen or R2 signifies chlorine, bromine, fluorine or a lower alkyl radical and R3 signifies hydrogen, chlorine, bromine, fluorine or an alkyl, alkylthio or lower alkoxy radical or trifluoromethyl, and their addition salts acid, characterized in that of a compound of general formula **(See formula)** wherein R2 and R3 have the meaning indicated above and R1 means the methyl or benzyl radical, the methyl or benzyl radical is cleaved and, if desired, mixtures of the compounds in which the 4a/5 hydrogen atoms are trans and 4a/9b hydrogen atoms are trans, and where 4a/5 hydrogen atoms are trans and 4a/9b hydrogen atoms are cis, they are separated into their different isomers and/or compounds of formula I obtained are transformed into their acid addition salts.
