Reaction Steps

Protocol T was followed using 4-Chloro-3-isopropyl-5-trifluoromethyl-1-H-pyrazol, K2CO3, 1-[4-(4-Chloro-3-methoxyphenyl)-piperazine-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=2/3, Rf=0.45) afforded the title compound as white solid. 1H NMR (400 MHz, CDCl3); 7.19-7.22 (d, 2H), 6.38-6.48 (m, 2H), 5 (s, 2H), 3.86 (s, 3H), 3.62-3.78 (m, 4H), 3.08-3.18 (m, 4H), 2.98-3.04 (m, 1H), 1.35-1.41 (d, 6H). 13C NMR (400 MHz, CDCl3): 163.8, 154.8, 150.5, 130, 109.8, 102, 56.4, 52.8, 50, 49.8, 45.2, 42.6, 26.8, 20.
