Potassium Carbonate → 2-[3-(4-chlorophenyl)-4-(3-fluorophenylmethyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-1-yl]-N-[3-(tri-fluoromethyl)phenylmethyl]acetamide

Participants

Reaction Steps

200 mg (0.66 mmol) of 5-(4-chlorophenyl)-4-(3-fluorophenylmethyl)-2,4-dihydro-3H-1,2,4-triazol-3-one from Example 41A, 193 mg (0.69 mmol) of 2-chloro-N-[3-(trifluoromethyl)phenylmethyl]-acetamide [preparable according to EP 0 163 607, Example 28] and 182 mg (1.32 mmol) of potassium carbonate are suspended in 2.5 ml of acetonitrile and heated under reflux overnight. After cooling, this is diluted with water, and purified by preparative HPLC [Method 9] and 219 mg (64% of theory) of the target compound are thus obtained.
