Reaction Steps

Protocol T was followed using 4-Bromo-3-phenyl-5-trifluoromethyl-1H-pyrazole, K2CO3, 2-Chloro-1-[4-(4-chloro-3-methoxy-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=1/1, Rf=0.51) afforded the title compound as a white solid. 1H NMR (400 MHz, CDCl3): 7.42-7.52 (m, 5H), 7.18-7.22 (d, 1H), 6.38-6.42 (dd, 1H), 6.46-6.48 (d, 1H), 4.94 (s, 2H), 3.88 (s, 3H), 3.5-3.78 (m, 4H), 3.18 (s, 4H).
