실험 절차

To a stirred solution of 4-(1,3-dioxolan-2-yl)phenylamine (0.0826 g, 0.500 mmol) and N,N-diisopropylethylamine (348 μL, 2.00 mmol) in DCM (2.0 mL) at room temperature was added a solution of biphenyl-2-ylcarbamic acid 1-{2-[(3-chlorocarbonylphenyl)methylcarbamoyl]ethyl}piperidin-4-yl ester (0.260 g, 0.500 mmol) in DCM (1.0 mL). The resulting mixture was stirred at room temperature for 1 h. LC-MS (Method 10-90) showed product was present (Rt 3.41 min; m/z 649.4 [M+H]+. Saturated aqueous sodium bicarbonate solution was added and the layers were separated. The organic layer was dried over sodium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel flash chromatography (0-5% MeOH in DCM) to give the title compound (345 mg containing some solvent residue, ca. 100% yield) as a brown oil.
