실험 절차

To a solution of 3-aminopropionic acid ethyl ester (41 mg, 0.268 mmol) and Et3N (0.082 mL, 0.730 mmol) is added a solution of (4-{4-[2-(3-Chlorophenylamino)-oxazol-5-yl]-phenyl}-cyclohexyl)-acetic acid (100 mg, 0.243 mmol) in DMF (4 mL), HATU (102 mg, 0.268 mmol) and iPr2NEt (0.127 mL, 0.73 mmol). The reaction mixture is allowed to stir at ambient temperature for 18 h. Water is added and EtOAc is used to extract. The organic layer is washed with brine, dried with Na2SO4 and concentrated to give the title compound (140 mg) as a tan solid: 1H NMR (400 MHz, DMSO-d6) δ ppm 1.02-1.13 (m, 2H) 1.18 (t, J=7.07 Hz, 3H) 1.38-1.50 (m, 2H) 1.71 (dd, J=7.71, 4.17 Hz, 1H) 1.78 (t, J=12.63 Hz, 4H) 1.98 (d, J=6.57 Hz, 2H) 2.44 (t, J=6.82 Hz, 2H) 3.25-3.28 (m, 2H) 4.06 (q, J=7.07 Hz, 2H) 6.99 (ddd, J=7.89, 1.96, 1.01 Hz, 1H) 7.27-7.35 (m, 1H) 7.29 (d, J=8.59 Hz, 2H) 7.40 (s, 1H) 7.50 (d, J=8.34 Hz, 1H) 7.47-7.52 (m, 1H) 7.85 (t, J=2.02 Hz, 1H) 7.88 (t, J=5.81 Hz, 1H) 10.52 (s, 1H); (M+H)+510.2.
