Participants

Reaction Steps

50.0 mg (0.160 mmol) of 2-[3-(4-chlorophenyl)-4-(2-methoxyethyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-acetic acid from Example 90A, 30.9 mg (0.176 mmol) of 3-trifluoromethylbenzyl-amine and 40.0 mg (0.209 mmol) of HOBt are placed in 2 ml of dimethylformamide and treated with 26.0 mg (0.192 mmol) of EDC hydrochloride. This is stirred overnight at room temperature, then stirred with 15 ml of water and the resulting precipitate recovered by filtration. The crude product is washed with water and dried in vacuo. 66.9 mg (89% of theory) of the target compound are thus obtained.
