A quantity of 58 mg (0.11 mmol) of [4-(4-chlorophenyl)-2-oxo-3-(3,3,3-trifluoro-2-hydroxypropyl)-2,3-dihydro-1H-imidazol-1-yl]acetic acid from Example 184A was dissolved in 2 ml of DMF, and the solution was admixed with 28 mg (0.15 mmol) of EDC and with 20 mg (0.15 mmol) of HOBt and subsequently stirred at room temperature for 20 minutes. Then 42 mg (0.12 mmol) of the compound from Example 183A were added and the mixture was left with stirring at room temperature for 16 h. For work-up, 100 μl of 1N hydrochloric acid were added and the crude product was purified directly by preparative HPLC [Method 19]. This gave 13 mg (18% of theory) of the target compound.
