Versuchsvorschrift

40.0 mg (0.119 mmol) of 4-(4-bromophenyl)-3-cyclopropyl-2-oxo-2,3-dihydro-1H-imidazol-1-yl]-acetic acid from Example 129A, 24.7 mg (0.130 mmol) of 1-[3-(trifluoromethyl)phenyl]ethylamine and 19.2 mg (0.142 mmol) of HOBt are placed in 1.5 ml of dimethylformamide and treated with 29.6 mg (0.154 mmol) of EDC hydrochloride. This is stirred overnight at room temperature, then stirred with 15 ml of water, and the resulting precipitate is isolated and this crude product purified by preparative HPLC [Method 13]. 23 mg (38% of theory) of the target compound are thus obtained.
