Reaction Steps

Protocol T was followed using 4-Chloro-5-methyl-1H-pyrazol-3-ylamine, 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 colorless oil. 1H NMR (400 MHz, CDCl3): 7.02-7.08 (m, 2H), 6.94-7.0 (t, 2H), 4.85 (s, 2H), 4.2 (s, 2H), 3.80-3.88 (m, 4H), 3.14-3.34 (m, 4H), 2.34 (s, 3H). MS (ES) M+H expected 317.37, found 318.1. MS (ES) M+H expected 351.81, found 352.1.
