Reaction Steps

Protocol T was followed using 4-Chloro-5-Propyl-2H-pyrazole-3-carboxylic acid ethyl ester, K2CO3, 2-Chloro-1-[4-(4-fluoro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=3/7) afforded the title compound as a white solid. 1H NMR (400 MHz, CDCl3): 6.94-7.0 (m, 2H), 6.82-6.90 (dd, 2H), 5.0 (s, 2H), 4.36-4.40 (q, 2H), 3.62-3.82 (m, 4H), 3.04-3.18 (m, 4H), 2.58-2.66 (t, 2H), 1.64-1.76 (m, 2H), 1.34-1.38 (t, 3H), 0.94-1.0 (t, 3H). 13C NMR (400 MHz, CDCl3): 165, 160.2, 156.2, 152.4, 147, 133, 118.4, 118.2, 115.8, 115.4, 112.2, 61, 53, 50.6, 50.2, 45, 42, 30, 22.8, 14.4, 14.2.
