実験手順

Protocol T was followed using 4-Bromo-5-methyl-3-trifluoromethyl-1H-pyrazole, K2CO3, 2-Chloro-1-[4-(4-chloro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=2/3) afforded the title compound as white solid. 1H NMR (400 MHz, CDCl3): 6.96-7.1 (m, 2H), 6.84-6.89 (m, 2H), 5.2 (s, 2H), 3.6.2-3.8 (m, 4H), 3.0-3.16 (m, 4H), 2.32 (s, 3H). 13C NMR (400 MHz, CDCl3): 162, 146.4, 142.2, 118.5, 116.2, 52, 50.4, 46.2, 42.2, 15.2.
