Procedure

To a solution of 1 g (0.0034 Mol) of 1-(1H-benzimidazol-5-yl-methyl)-2-(4-methyl-piperidin-1-yl)-2-oxoethylamine and 1.1 g (0.011 Mol) of triethylamine in 30 ml of chloroform are added dropwise, at ambient temperature and with stirring, 0.96 g (0.0034 Mol) of 9-methyl-1,2,3,4-tetrahydro-carbazol-6-sulphonic acid chloride dissolved in 10 ml of chloroform. After 12 hours' stirring the mixture is evaporated down in vacuo and the residue obtained is chromatographed over a silica gel column (eluant: ethyl acetate/methanol=9:1). The eluate having an Rf value of 0.3 is collected and evaporated down in vacuo.
