実験手順

1,280 parts of a 20.7% strength by weight solution of γ-chlorobutyraldehyde in xylene (prepared by a method similar to that described in Houben-Weyl, Volume 7/1, pages 285-290, by catalytic hydrogenation of a solution of γ-chlorobutyric acid chloride in xylene), 490 parts of 3-(β-aminoethyl)-indole hydrochloride and 1,000 parts of isopropanol were stirred for 4 hours at 88° C., and the mixture was cooled and then filtered under suction to give 618 parts (87%) of 1-(γ-chloropropyl)-1,2,3,4-tetrahydro-β-carboline hydrochloride. After recrystallization from methanol, the substance had a melting point of 219°-221° C.
