Reaction Steps

70.0 mg (0.238 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 48.6 mg (0.238 mmol) of 2-(3,5-dichlorophenyl)propan-2-amine are placed in 2 ml of dimethylformamide and treated with 38.6 mg (0.286 mmol) of HOBt. After 10 mins' stirring, 59.4 mg (0.310 mmol) of EDC hydrochloride are added and the mixture is stirred overnight at room temperature. Without further workup, the mixture is purified directly by preparative HPLC [Method 10]. 70 mg (61% of theory) of the target compound are thus obtained.
