Dimethylformamide → 1-[4-(4-Bromo-3-methoxyphenyl)-piperazin-1-yl]-2-(4-chloro-3-phenyl-5-trifluoromethyl-pyrazol-1-yl)-ethanone

Participants

Reaction Steps

Protocol T was followed using 4-Chloro-5-phenyl-3-trifluoromethyl-1H-pyrazole, K2CO3, 2-Chloro-1-[4-(4-bromo-3-methoxy-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=2/3) afforded the title compound as a white solid. 1H NMR (400 MHz, CDCl3): 7.42–7.52 (m, 4H), 7.36–7.38 (d, 1H), 6.42–6.46 (d, 1H), 6.34–6.38 (dd, 1H), 4.72 (s, 2H), 3.88 (s, 3H), 3.74–3.78 (m, 2H), 3.54–3.58 (m, 2H), 3.12–3.18 (m, 4H). 13C NMR (400 MHz, CDCl3): 164, 156.2, 152, 132.6, 130.2, 130, 128.8, 110, 102.2, 56, 52, 50, 44.8, 42.
