Procedure

40.0 mg (0.121 mmol) of 2-[3-(3-chloro-4-methyl-2-thienyl)-4-isobutyl-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-acetic acid from Example 249A and 23.4 mg (0.133 mmol) of 3-trifluoromethyl-benzylamine are placed in 1.5 ml of DMF and treated with 19.7 mg (0.146 mmol) of HOBt. 30.2 mg (0.158 mmol) of EDC hydrochloride are added and the mixture is stirred overnight at RT. For the workup, the reaction mixture is stirred with about 15 ml of water and the resulting precipitate filtered off, washed with water and dried in vacuo. 43 mg (73% of theory) of the target compound are thus obtained.
