Participants

Reaction Steps

Protocol T was followed using 5-methyl-2H-pyrazole-3-carboxylic acid ethyl ester, K2CO3, 2-Chloro-1-[4-(4-fluoro-phenyl)-piperazin-1-yl]-ethanone and DMF. Column chromatography using a solvent mixture (hexane/ethyl acetate=1/1) afforded the title compound as a white solid. 1H NMR (400 MHz, CDCl3): 6.94-7.0 (m, 2H), 6.84-6.88 (dd, 2H), 6.58 (s, 1H), 5.04 (s, 2H), 4.3-4.38 (q, 2H), 3.62-3.80 (m, 4H), 3.02-3.14 (m, 4H), 2.3 (s, 3H), 1.32-1.38 (t, 3H). 13C NMR (400 MHz, CDCl3): 180, 165, 119, 116.2, 116, 109, 61.8, 52, 51.5, 50.8, 45.8, 42.6, 14.4, 10.2.
