Reaction Steps

Protocol T was followed using 5-amino-3-cyanomethyl-1H-pyrazole-4-carbonitrile, K2CO3, 2-Chloro-1-[4-(4-fluoro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=3/2) afforded the title compound as white solid. 1H NMR (400 MHz, CDCl3): 6.96-7.2 (m, 2H), 6.86-6.92 (m, 2H), 5.2 (s, 2H), 4.86 (s, 2H), 3.78-3.86 (m, 4H), 3.7 (s, 2H), 3.08-3.16 (m, 4H). MS (ES) M+H expected 367.39, found 368.1.
