Reaction Steps

Protocol T was followed using 4-Chloro-5-phenyl-3-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=2/3, Rf=0.92) afforded the title compound as a white solid. 1H NMR (400 MHz, CDCl3): 7.78–7.84 (m, 2H), 7.36–7.52 (m, 4H), 6.38–6.48 (m, 2H), 5.2 (s, 2H), 3.88 (s, 3H), 3.62–3.78 (m, 4H), 3.18–3.26 (s, 4H). 13C NMR (400 MHz, CDCl3) 164.4, 156, 150.4, 130.4, 130, 128.6, 110.2, 102.4, 56.4, 52, 50.4, 44.6, 42.
