A process for the preparation of hydroxy(cycloalkane/cyclokene) phenylethyl amine
of the general formula (III) comprising alkylation of its precursor amine of general
formula (II) which is in turn produced by an effective reduction process from its
precursor cyanide having the general formula (I) using Raney Nickel (CORMIII) as
catalyst where, either of R5 and R6 independently could be in meta or para position
and R5, R6 are independently hydrogen, hydroxyl, alkyl, alkanoyloxy, cyano, nitro,
alkylmercapto, amino, alkylamino, allkanamido, halo, trifluoromethyl, or taken
together methylenedioxy, n is 0, 1, 2, 3, 4, R7 is hydrogen of alkyl of 1-7 carbon
atom, R1 IH or alkyl of 1-3 carbon atom and R2 is alkyl 1-3 carbon atom, the dotted
line represents optional unsaturation. Compounds of formulae IV, V and VI are respectively
derivatives of compounds I, II and III respectively.
