Procedure

50 mg (0.163 mmol) of 2-(4-[4-chlorophenyl]-3-cyclopropyl-2-oxo-2,3-dihydro-1H-imidazol-1-yl)-propionic acid from Example 131A, 31.4 mg (0.179 mmol) of 3-trifluoromethylbenzylamine, 40.6 mg (0.212 mmol) of EDC hydrochloride and 26.4 mg (0.196 mmol) of HOBt are dissolved in 1 ml of dry dimethylformamide and stirred overnight at room temperature. The mixture is partitioned between water and dichloromethane, and the separated organic phase is dried over sodium sulphate and concentrated. The crude product that remains is purified by flash chromatography on silica gel (eluent: first dichloromethane, then dichloromethane/methanol 100:1→50:1). 42 mg (56% of theory) of the target compound are thus obtained.
