実験手順

To a solution of 1-{4-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-phenyl}-piperidine-4-carboxylic acid (229.5 mg, 0.5 mmol) in DMF (4 mL) was added piperidine-4-carboxylic acid ethyl ester (79 mg, 0.5 mmol), PyBrop (233.1 mg, 0.5 mmol) and triethylamine (0.1 mL). The mixture was stirred overnight and solvents were evaporated. The residue was extracted with ethyl acetate and water. After the evaporation of solvents, the residue was purified through flash column chromatography using ethyl acetate and hexanes. The desired fraction was evaporated and triturated with ether and petroleum ether (2:1) to give a yellow solid as 1-(1-{4-[(2-phenyl-5-trifluoromethyl-oxazole-4-carbonyl)-amino]-phenyl}-piperidine-4-carbonyl)-piperidine-4-carboxylic acid ethyl ester. LC-MS showed a single peak with a retention time of 3.54 min. LRMS calcd for C31H33F3N4O5 (M+H) 599.24, obsd 599.3
