実験手順

To a solution of the product from Example 37B (17.7 mg, 0.065 mmol) and the product from Example 37E (50 mg, 0.130 mmol) in anhydrous DMSO (1.3 mL) was added HATU (27.1 mg, 0.071 mmol) and Hunig's Base (0.015 mL, 0.084 mmol). The resulting mixture was stirred at rt for 30 min, and was then partitioned between H2O (5 mL) and EtOAc (3×5 mL). The combined organic layers were dried over Na2SO4. The drying agent was filtered off, and solvent was removed in vacuo. The crude product was purified by column chromatography on silica gel using a solvent gradient of 0-5% MeOH in CH2Cl2 to give the title compound (20 mg, 24%). 1H NMR (400 MHz, DMSO-D6) δ ppm 0.88 (d, J=6.72 Hz, 3 H), 0.93 (d, J=6.72 Hz, 3 H), 1.11 (s, 9 H), 1.52-1.66 (m, 2 H), 1.79-2.06 (m, 4 H), 2.06-2.20 (m, 1 H), 2.34-2.47 (m, 2 H), 3.52 (s, 3 H), 3.56-3.67 (m, 1 H), 3.74-3.87 (m, 1 H), 4.02 (t, J=8.51 Hz, 1 H), 4.42 (dd, J=8.08, 4.83 Hz, 1 H), 4.83-4.94 (m, 2 H), 5.02 (d, J=7.16 Hz, 0.5 H), 5.08 (d, J=7.59 Hz, 0.5 H), 6.18 (d, J=8.78 Hz, 2 H), 6.48 (d, J=8.35 Hz, 2 H), 6.84 (d, J=8.35 Hz, 2 H), 6.93 (d, J=8.89 Hz, 2 H), 7.11 (d, J=8.57 Hz, 2 H), 7.31 (d, J=8.35 Hz, 1 H), 7.48 (d, J=8.57 Hz, 2 H), 9.97 (s, 1 H); MS (ESI) m/z 640.3 (M+H)+.
