Reaction Steps

To a solution of the product from Example 53 (0.35 g, 0.83 mmol) in anhydrous CH2Cl2 (50 mL) was added methanesulfonyl chloride (194 μL, 2.49 mmol) and pyridine (1.34 mL, 16.6 mmol). The resulting mixture was stirred at room temperature for 16 h and concentrated in vacuo. The crude product was purified by C-18 reverse-phase HPLC using an acetonitrile:H2O (0.1% TFA) gradient to give the title compound (19 mg, 4%). 1H NMR (300 MHz, DMSO-d6) δ 13.09 (s, 1H) 11.41 (d, J=1.84 Hz, 1H) 7.96 (d, J=1.47 Hz, 1H) 7.77 (d, J=8.09 Hz, 1H) 7.57 (dd, 1H) 7.42 (d, J=8.09 Hz, 1H) 7.25-7.32 (m, 2H) 5.64 (dd, J=8.09, 2.21 Hz, 1H) 3.25 (s, 3H) 3.02 (s, 3H) 1.40 (s, 9H).
