실험 절차

3-(Acetylamino)-2-[4-(tert-butoxycarbonyl)phenyl]propanoic acid (222 mg, 0.72 mmol), EDCI (207 mg, 1.08 mmol), and HOBT (127 mg, 0.94 mmol) were dissolved in DMF (7 mL) and stirred for 5 minutes before adding aniline (99 μL, 1.08 mmol). After stirring at room temperature for 18 h, the solution was concentrated. The resulting residue was taken up in EtOAc, washed (water, sat. NaHCO3, brine), dried (MgSO4), and concentrated. Flash chromatography on silica (0-4% MeOH/DCM) afforded tert-butyl 4-{1-[(acetylamino)methyl]-2-anilino-2-oxoethyl}benzoate as an off-white solid. 1H NMR (DMSO-d6) δ10.18 (s, 1H), 8.08 (t, J=5.9 Hz, 1H), 7.84 (d, J=8.5 Hz, 2H), 7.56 (d, J=7.6 Hz, 2H), 7.46 (d, j=8.2 Hz, 2H), 7.25 (t, J=7.9 Hz, 2H), 7.00 (t, J=7.5 Hz, 1H), 4.03 (dd, J=8.2, 6.3 Hz, 1H), 3.51 (ddd, J=13.2, 8.4, 5.0 Hz, 1H), 3.42 (dt, J=12.9, 6.5 Hz, 1H), 1.74 (s, 3H), 1.50 (s, 9H). MS (ESI) calcd [M+H]+ 383.2, found 383.1.
