実験手順

To a solution of the product from Example 28, Part F (90 mg, 0.232 mmol) in anhydrous methanol (3 mL) was added 4 M HCl in 1,4-dioxane (0.579 mL, 2.317 mmol). The resulting mixture was stirred at room temperature for 18 hours, and the volatiles were removed in vacuo. The residue was suspended in N,N-dimethylformamide (3 mL), 2-hydroxy-2-(3-(trifluoromethyl)phenyl)acetic acid (0.056 g, 0.255 mmol), O-(7-azabenzotriazol-1-yl)-N,N,N′,N′-tetramethyluronium hexafluorophosphate (HATU, 0.106 g, 0.278 mmol), and N-methyl morpholine (0.117 g, 1.158 mmol) were added, and the resulting solution was stirred at room temperature for 16 hours. The mixture was partitioned between water and ethyl acetate. The organic extract was washed with brine, dried over MgSO4, filtered, and concentrated in vacuo. The crude product was purified by column chromatography on silica gel using a solvent gradient of 0-7% methanol in dichloromethane. The title compound was obtained as a colorless solid (0.065 g, 57% yield). 1H NMR (400 MHz, pyridine-d5, 90° C.) δ ppm 8.09-7.99 (m, 2H), 7.98 (d, J=1.4 Hz, 1H), 7.87-7.79 (m, 1H), 7.56 (d, J=1.3 Hz, 1H), 7.43 (t, J=7.8 Hz, 1H), 5.94-5.85 (m, 1H), 5.40 (t, J=4.1 Hz, 1H), 4.90-4.15 (m, 3H), 4.12 (d, J=13.5 Hz, 1H), 3.73 (dd, J=13.5, 4.3 Hz, 1H), 3.50-2.15 (m, 6H), 2.07-1.79 (m, 2H), 1.05-0.93 (m, 2H), 0.95-0.83 (m, 2H).); MS (ESI) m/z 491 (M+H)+.
