Procedure

Title compound was prepared following the HATU mediated coupling protocol P, wherein 1-(3-Chlorophenyl)piperazine 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) 7.23 (t, 1H), 7.19 (s, 1H), 6.90 (d, 1H), 6.79 (d, 1H), 5.37 (s, 2H), 3.58 (m, 4H), 3.29 (m, 2H), 3.19 (m, 2H), 2.18 (s, 3H) ppm; MS (ES) M+H expected=421.1, found=421.0.
