Reaction Steps
Protocol T was followed using 3-Chloro-1H-indazole, K2CO3, 2-Chloro-1-[4-(4-fluoro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=1/4) afforded the title compound as a white solid. 1H NMR (400 MHz, CDCl3); 7.64-7.70 (m, 1H), 7.38-7.48 (m, 2H), 7.18-7.26 (m, 2H), 6.94-7.0 (m, 2H), 6.82-6.88 (dd, 2H), 5.2 (s, 2H), 3.72-3.82 (m, 4H), 3.02-3.08 (m, 4H). 13C NMR (400 MHz, CDCl3): 165, 158.2, 142.8, 134.8, 128.8, 128.4, 122, 121.6, 118.8, 118.6, 115.4, 115.2, 110.6, 110.0, 51.8, 50.6, 50.2, 45.2, 42.
