Participants

Reaction Steps

2.7 g (6.1 mmol) of 4-[(5-benzenesulphonylamino-1-carboxymethyl-1H-benzimidazol-2-yl)-methyl]-benzonitrile, 0.85 g (6.1 mmol) of glycine-ethyl ester-hydrochloride and 1.5 g (15 mmol) of triethylamine are dissolved in 80 ml dimethylformamide and after the addition of 2.4 g (7.5 mmol) of O-(benzotriazol-1-yl)-N,N,N',N'-tetramethyluroniumtetrafluoroborate the mixture is stirred for 16 hours at ambient temperature. The solvent is evaporated off, the residue chromatographed on silica gel and eluted with methylene chloride/ethanol 99:1 and 98:2. The desired fractions are concentrated by evaporation, the residue is triturated with ether, suction filtered and dried.
