Procedure

Protocol T was followed using 3-Amino-5-methyl-1H-pyrazole-4-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=1/4) afforded the title compound as a colorless oil. 1H NMR (400 MHz, CDCl3): 6.94-7.1 (m, 2H), 6.84-6.88 (m, 2H), 5.52 (s, 2H), 4.78 (s, 2H), 4.24-4.32 (q, 2H), 3.74-3.82 (m, 4H), 3.0-3.1 (m, 4H), 2.3 (s, 3H), 1.31-1.38 (t, 3H). MS (ES) M+H expected 389.43, found 390.1.
