Versuchsvorschrift
A mixture of 2,3,4,9-tetrahydro-1H-carbazole-7-carboxylic acid and 2,3,4,9-tetrahydro-1H-carbazole-5-carboxylic acid was obtained by allowing cyclohexanone and 3-hydrazinobenzoic acid to undergo the reaction under heating in acetic acid. By separating and purifying this mixture by a silica gel column chromatography, 2,3,4,9-tetrahydro-1H-carbazole-5-carboxylic acid [Reference Example 16a: FAB: 216 (M+H)+] and 2,3,4,9-tetrahydro-1H-carbazole-7-carboxylic acid [Reference Example 16b: FAB: 216 (M+H)+] were obtained.
