Procedure

DIPEA (74 mg, 0.1 mL, 0.63 mmol) was added drop wise to 4-(phenyl-amino)-benzoic acid (45 mg, 0.21 mmol) in DMF (5 mL). EDCI (100 mg, 0.52 mmol) and HOBT (34 mg, 0.25 mmol) were added consecutively and, after 10 minutes, 2-amino-1-[4-(2-chloro-5-trifluoromethyl-benzoyl)-piperazin-1-yl]-ethanone in its HCl salt form (97 mg, 0.25 mmol) was added. The resulting mixture was stirred at room temperature overnight. Cold water was then added and the product was extracted with EtOAc and the organic layer was washed with brine. The organic phase was dried over Na2SO4 and concentrated under reduced pressure to get the residue. The obtained residue was purified by column chromatography (using silica gel of 60-120 mesh and 70% EtOAc in Hexane as eluent) to afford 60 mg (52% yield) of N-{2-[4-(2-chloro-5-trifluoromethyl-benzoyl)-piperazin-1-yl]-2-oxo-ethyl}-4-phenylamino-benzamide. LC-MS purity: 98.43%. 1H-NMR (DMSO-d6): δ 8.6 (s, 1H), 8.3 (t, 1H), 7.9 (d, 1H), 7.8 (m, 4H), 7.3 (t, 2H), 7.2 (d, 2H), 7.1 (d, 2H), 6.9 (t, 1H), 4.1 (dd, 2H), 3.6 (m, 6H), 3.2 (m, 2H).
