Versuchsvorschrift

Protocol T was followed using 4-Bromo-5-phenyl-1H-pyrazol-3-ylamine, K2CO3, 2-Chloro-1-[4-(4-chloro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=1/4) afforded the title compound as white solid. 1H NMR (400 MHz, CDCl3): 7.7–7.8 (m, 2H), 7.24–7.3 (m, 3H), 6.8–6.92 (m, 2H), 6.74–6.78 (m, 2H), 4.9 (s, 2H), 4.2 (s, 2H), 3.6–3.7 (m, 4H), 2.86–3.04 (m, 4H). 13C NMR (400 MHz, CDCl3): 164, 146, 145, 128, 127, 118, 114.8, 60.2, 50.4, 50, 48.8, 46, 42, 22.
