実験手順

Into a round bottom flask was placed a solution of 2-(3-((3-((4-(piperidin-1-yl)-2-((1-(3-(trifluoromethyl)phenyl)-1H-pyrazol-3-yl)carbamoyl)phenyl)carbamoyl)benzyl)thio)-phenyl)acetic acid 23 (0.119 mmol, 1 equiv) in acetonitrile (0.5 mL), and DIPEA (78.9 mg, 0.612 mmol, 4 equiv). To this was added a solution of tert-butyl 3-(2-(2-(2-(methylamino)ethoxy)ethoxy)ethoxy)propanoate 8b (33.08 mg, 0.127 mmol, 1.1 equiv) in acetonitrile (0.5 mL), followed by HATU (57.9 mg, 0.153 mmol, 1.2 equiv). The mixture was stirred at room temperature. The reaction progress was monitored by LCMS. After 1 h, more 8b (15 mg) was added to the solution, and the solution was stirred another 30 min. The solvent was removed by evaporation at reduced pressure. The residue was dissolved in DCM (1 mL). To this was added TFA (0.5 mL). The solution was stirred for 1 h and then the solvent was evaporated at reduced pressure. The crude product was purified by reverse phase HPLC eluting with a water/CH3CN gradient containing 0.05% TFA. Lyophilization gave 37 mg of product. 1H NMR (400 MHz, dmso) δ 11.55 (s, 1H), 11.46 (s, 1H), 8.65 (d, J=2.6 Hz, 1H), 8.33 (d, J=8.5 Hz, 1H), 8.16 (s, 1H), 8.12 (d, J=7.9 Hz, 1H), 8.05 (t, J=5.2 Hz, 1H), 7.94 (s, 1H), 7.78-7.67 (m, 3H), 7.61 (d, J=7.5 Hz, 2H), 7.55 (d, J=7.4 Hz, 1H), 7.45 (t, J=7.7 Hz, 1H), 7.22 (s, 1H), 7.17 (d, J=4.9 Hz, 3H), 7.01 (s, 3H), 4.30 (s, 3H), 3.54 (t, J=6.4 Hz, 4H), 3.43 (s, 14H), 3.41-3.16 (m, 15H), 3.16-3.09 (m, 3H), 2.39 (t, J=6.4 Hz, 3H), 1.76-1.66 (m, 4H), 1.61-1.52 (m, 2H).
