反応手順
Protocol T was followed using 4-Bromo-3,5-dimethyl-pyrazole, K2CO3, 2-Chloro-1-[4-(4-fluoro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=1/1) afforded the title compound as a white solid. 1H NMR (400 MHz, CDCl3): 6.95-7.1 (m, 2H), 6.84-6.92 (dd, 2H), 4.90 (s, 2H), 3.62-3.82 (m, 4H), 3.02-3.12 (m, 4H), 2.24-2.34 (d, 6H). 13C NMR (400 MHz, CDCl3): 165, 158.4, 156.6, 150.6, 146.8, 141.4, 119, 115.6, 115.2, 52.6, 51.6, 50.4, 45.2, 42.2, 14.8, 12.6.
