Versuchsvorschrift

To a solution of the amine 9 (80 mg, 0.235 mmol), 3-oxo-3-(phenylamino)propanoic acid (1) (42 mg, 0.235 mmol) and BOP (114.6 mg, 0.259 mmol) in DMF (2.4 mL), DIPEA (0.164 mL, 0.941 mmol) was added and the mixture was stirred at room temperature for 2 h. The reaction mixture was partitioned between EtOAc and water. Organic phase was collected, washed with H2O and brine, dried over anhydrous Na2SO4 and concentrated. The residue was purified by flash chromatography (EtOAc/MeOH 95:5) followed by crystallization (MeOH) to afford the title compound 5b (11 mg, 9% yield). 1H NMR (DMSO-d6) δ (ppm): 10.55 (s, 1H), 10.19 (s, 1H), 8.5 (d, J=5.4 Hz, 1H), 7.86 (m, 2H), 7.59 (m, 2H), 7.49 (t, J=8.8 Hz, 1H), 7.41 (m, 2H), 7.30 (m, 2H), 7.05 (m, 2H), 6.69 (d, J=5.4 Hz, 1H), 3.99 (s, 3H), 3.52 (s, 2H). MS (m/z): 502.2 (M+H).
