Procedure

50.0 mg (0.170 mmol) of [3-(4-chlorophenyl)-4-cyclopropyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-acetic acid from Example 88A and 32.8 mg (0.187 mmol) of 3-trifluoromethylbenzylamine are placed in 2 ml dimethylformamide and treated with 27.6 mg (0.204 mmol) of HOBt. After 10 mins' stirring, 42.4 mg (0.221 mmol) of EDC hydrochloride are added and the mixture stirred overnight at room temperature. For the workup, the reaction mixture is partitioned between dichloromethane and water, and the organic phase is separated, dried over sodium sulphate and concentrated. The residue is purified by flash chromatography on silica gel (eluent: dichloromethane/methanol first 200:1, then 100:1) and thus yields 76 mg (99% of theory) of the target compound.
