A quantity of 30 mg (0.08 mmol) of [3-(4-chlorophenyl)-4-(2-fluorobenzyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetic acid (preparation according to WO2007/134862, Example 154A) was dissolved in 1 ml of DMF, and the solution was admixed with 21 mg (0.11 mmol) of EDC and with 15 mg (0.11 mmol) of HOBt and subsequently stirred at room temperature for 20 minutes. Then 23 mg (0.09 mmol) of the compound from Example 180A were added and the mixture was left with stirring at room temperature for 16 h. For work-up, 50 μl of 1N hydrochloric acid were added and the crude product was purified directly by preparative HPLC [Method 19]. This gave 34 mg (69% of theory) of the target compound.
