  • Patent number: 4140691
    Abstract: The invention provides a process for preparing indole derivatives in which a compound containing an indole ring linked to an acylamido piperidine ring by a carbonyl alkylene group between the nitrogen of the piperidine and the 3-position of the indole is reduced with alkali-metal borohydride in special solvents so that the carbonyl group is reduced to a CH.sub.2 group.
