실험 절차

DIPEA (170 mg, 0.22 mL, 1.31 mmol) was added to a stirred solution of 2-phenyl-thiazole-5-carboxylic acid (90 mg, 0.43 mmol) in DMF (2 mL). HOBT (71 mg, 0.52 mmol) and EDCI (100 mg, 0.52 mmol) were then added at room temperature. After 2 minutes 2-amino-1-[4-(2-trifluoromethyl-benzoyl)-piperazin-1-yl]-ethanone hydrochloride salt (185 mg, 0.52 mmol) was added and the resulting mixture was stirred at room temperature overnight. Cold water was then added and then extrated with ethyl acetate. The organic layer was washed with brine and dried over Na2SO4 and concentrated under reduced pressure to afford 77.1 mg (35%) of 2-phenyl-thiazole-5-carboxylic acid {2-oxo-2-[4-(2-trifluoromethyl-benzoyl)-piperazin-1-yl]-ethyl}-amide. LCMS Purity: 95.1%. 1H NMR (DMSO-d6): δ 9.0-8.9 (m, 1H), 8.54-8.5 (s, 1H), 8.0 (m, 2H), 7.9-7.64 (m, 3H), 7.6-7.5 (m, 4H), 4.24-4.1 (m, 2H), 3.8-3.6 (m, 4H), 3.5-3.4 (m, 2H), 3.2-3.0 (m, 2H).
