実験手順

A mixture of the product of Example 42 (90 mg, 0.26 mmol), iPr2NEt (0.078 mL, 0.45 mmol), and cyclohexyl carbonochloridate (51.2 mg, 0.315 mmol) in DCM (4 mL) was stirred at room temperature for 8 hours, diluted with Et2O, washed with sat NaHCO3 and brine, dried (MgSO4), filtered, concentrated, and chromatographed (17-25% EtOAc/DCM) to give the title compound. 1H NMR (300 MHz, DMSO-d6) δ ppm 11.60 (s, 1H), 8.32 (dd, J=7.8, 1.4 Hz, 1H), 8.10 (d, J=8.0 Hz, 1H), 7.97-8.03 (m, 1H), 7.91 (td, J=7.5, 1.2 Hz, 1H), 7.60-7.65 (m, 1H), 7.41 (s, 4H), 4.47-4.51 (m, 3H), 3.67 (s, 2H), 1.58-1.84 (m, 4H), 1.41-1.54 (m, 1H), 1.10-1.35 (m, 4H); MS (ESI−) M/Z 467 (M−H)−.
