HCID 587780144-{4-[2-(4-Chloro-5-methyl-3-trifluoromethyl-pyrazol-1-yl)-acetyl]-piperazin-1-yl}-benzoic acid methyl ester

Procedure

Title compound was prepared following the HATU mediated coupling protocol P, wherein 4-Piperazin-1-yl-benzoic acid methyl ester and (4-Chloro-5-methyl-3-trifluoromethyl-pyrazol-1-yl)-acetic acid were used as the coupling components, to give the product as a solid: 1H NMR (DMSO-d6, 400 MHz) 7.78 (d, 2H), 6.98 (d, 2H), 5.38 (s, 2H), 3.71 (s, 3H), 3.60 (m, 4H), 3.46 (m, 2H), 3.37 (m, 2H), 2.19 (s, 3H) ppm; MS (ES) expect M+H=445.1, found 445.0.
