Reaction Steps
Protocol T was followed using 4-Amino-3-heptafluoropropyl-5-methyl-1H-pyrazole, K2CO3, 2-Chloro-1-[4-(4-fluoro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=1/4) afforded the title compound as colorless oil. 1H NMR (400 MHz, CDCl3); 6.92-7.02 (m, 4H), 5.14 (s, 2H), 3.64-3.82 (m, 4H), 3.6 (s, 2H), 3.1-3.22 (m, 4H), 2.16 (s, 3H). 13C NMR (400 MHz, CD6CO): 160.4, 158, 146, 144.2, 119.8, 118.2, 52, 50.8, 50.6, 46, 42, 12.2.
