Diisopropylethylamine → 5-(4-Chlorophenyl)-4-(4-methoxybenzyl)-2-({1-[2-(trifluoromethyl)benzyl]-1H-1,2,4-triazol-5-yl}-sulfonyl)-2,4-dihydro-3H-1,2,4-triazol-3-one

Participants

Reaction Steps

334 mg (0.75 mmol) of the compound from Example 94A were dissolved in 5 ml of dichloromethane, and 154 μl (0.93 mmol) of N,N-diisopropylethylamine were added. 223 mg (0.93 mmol) of 2-(trifluoromethyl)benzyl bromide dissolved in 0.5 ml of dichloromethane were then added, and the mixture was stirred at RT for 20 h. For work-up, the mixture was concentrated under reduced pressure and the crude product was purified chromatographically [Method 19]. This gave 245 mg (54% of theory) of the target compound.
