실험 절차

DIPEA (98 mg, 0.76 mmol) was added to a stirred solution of (4-benzyloxy-benzoylamino]-acetic acid (50 mg, 0.17 mmol) in DMF (3 mL). HOBT (25.8 mg, 0.19 mmol) and EDCI.HCl (83 mg, 0.43 mmol) were added at room temperature. After 2 minutes, piperazine-1-yl-(2-trifluoromethyl-phenyl)-methanone hydrochloride (61.5 mg, 0.21 mmol). The resulting mixture was stirred at room temperature overnight. The mixture was diluted with cold water and the resulting precipitate was filtered, washed with hexane and dried to afford 93 mg (99% yield) of 4-benzyloxy-N-{2-oxo-2-[4-(2-trifluoromethyl-benzoyl)-piperazin-1-yl]-ethyl}-benzamide. LC-MS purity: 87%, 1H NMR (DMSO): δ 8.5 (s, 1H,), 7.8 (m, 5H), 7.5 (s, 1H), 7.4 (m, 4H), 7.1 (d, 2H), 5.2 (s, 2H), 4.2 (d, 2H), 3.7 (m, 4H), 3.5 (s, 2H), 3.4 (s, 2H), 3.3 (s, 2H).
