Participants

Reaction Steps

318 mg (1.26 mmol) of [4-(4-chlorophenyl)-2-oxo-2,3-dihydro-1H-imidazol-1-yl]-acetic acid from Example 233A are placed in 10 ml DMF and treated with 221 mg (1.64 mmol) of HOBt and 314 mg (1.64 mmol) of EDC hydrochloride. After 10 mins' stirring, 332 mg (1.64 mmol) of 1-methyl-1-[(3-trifluoromethyl)phenyl]ethylamine from Example 1A are added and the mixture is stirred overnight at room temperature. For the workup, the reaction mixture is stirred with 100 ml water. Next, the resulting precipitate is suction-filtered, washed with water and dried under high vacuum. Further purification is effected by preparative HPLC [Method 10]. 209 mg (38% of theory) of the target compound are thus obtained.
