실험 절차
(S)-tert-butyl 4-(2-amino-4-(1-phenylethylcarbamoyl)phenylthio)-phenylcarbamate (50 mg, 0.1078 mmol) and the product of Example 431F (24.5 mg, 0.1186 mmol) were heated at reflux in anhydrous ethanol (2 mL) under a nitrogen atmosphere for one hour. The reaction was cooled and concentrated by rotary evaporation. The residue was purified by silica gel flash chromatography eluting with 3:97 methanol/methylene chloride to afford the title compound as an off-white solid (51 mg, 0.0805 mmol, 68%). 1H NMR (300 MHz, DMSO-D6) δ ppm 1.31 (d, J=6.99 Hz, 6 H) 1.45 (d, J=7.35 Hz, 3 H) 1.47 (s, 9 H) 3.03-3.21 (m, 1 H) 5.01-5.29 (m, 1 H) 6.96 (d, J=8.46 Hz, 1 H) 7.16-7.25 (m, 1 H) 7.26-7.43 (m, 3 H) 7.32 (d, J=8.09 Hz, 2 H) 7.51 (d, J=8.82 Hz, 2 H) 7.55-7.63 (m, 2 H) 7.72 (dd, J=8.46, 1.47 Hz, 1 H) 7.94 (d, J=1.47 Hz, 1 H) 8.41 (d, J=8.82 Hz, 1 H) 8.44 (s, 1 H) 8.80 (d, J=8.09 Hz, 1 H) 9.58 (s, 1 H) 9.95 (s, 1 H); MS (ESI+) m/z 634 (M+H)+; MS (ESI−) m/z 632 (M−H)−.
