실험 절차

DIPEA (92 mg, 0.125 mL, 0.72 mmol) was added drop wise to 4-(Methyl-phenyl-amino)-benzoic acid (55 mg, 0.24 mmol) in DMF (5 mL). EDCI (115 mg, 0.6 mmol) and HOBT (39 mg, 0.28 mmol) were added consecutively and, after 10 minutes, 2-amino-1-[4-(2-trifluoromethyl-benzoyl)-piperazin-1-yl]-ethanone in its TFA salt form (124 mg, 0.289 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 Preparative HPLC [(Column-Zorbax XDB C18-21.2×150 mm, mobile phase-0.1% TFA in water (A)/acetonitrile (B), gradient: (Time): (% B)-0:20; 2:30; 8:70)]) to afford 34 mg (26% yield) of 4-(Methyl-phenyl-amino)-N-{2-oxo-2-[4-(2-trifluoromethyl-benzoyl)-piperazin-1-yl]-ethyl}-benzamide. LC-MS purity: 97.62%. 1H-NMR (CDCl3): δ 7.7 (m, 3H), 7.6 (m, 2H), 7.4 (q, 3H), 7.2 (m, 2H), 7.1 (m, 1H), 6.8 (d, 2H), 4.3 (dd, 1H), 4.2 (dd, 1H), 4.0 (m, 1H), 3.9 (m, 1H), 3.7 (m, 3H), 3.4 (m, 1H), 3.3 (s, 3H), 3.2 (m, 2H).
