Participants

Reaction Steps

A solution of 3-phenyl propionic acid (9.7 mg) in dry dimethylformamide (0.6 ml) was treated with N-{(dimethylamino)(1H-1,2,3-triazolo[4,5-b]pyridin-1-yl)methylene}-N-methylmethanaminium hexafluorophosphate N-oxide (21 mg) and diisopropylethylamine (12 μl). After stirring at ambient temperature for 30 minutes, 4-cyclopentylamino-benzenesulfonic acid 2-amino-3H-benzoimidazol-5-yl ester (20 mg) was added and the mixture stirred at room temperature for a further 3 hours. The solvent was removed under vacuo and the residue was purified by triggered LC/MS to give 4-cyclopentylamino-benzenesulfonic acid 2-(3-phenyl-propionylamino)-1H-benzoimidazol-5-yl ester as an off-white solid (11 mg). Mass spectrum: 505 [M+H]+; retention time=4.59 minutes.
