Reaction Steps

The product from Example 68A, (0.021 g) in dioxane (0.5 mL) and 4N HCl in dioxane (0.5 mL) was heated at 70° C. for 24 hours, cooled, and concentrated. Purification by reverse phase HPLC (C18, CH3CN/water (0.1% TFA), 10-100%) afforded the title compound (0.007 g, 27%) as the TFA salt. 1H NMR (500 MHz, DMSO-d6/D2O) δ ppm 7.64 (dd, J=8.70, 2.29 Hz, 1H) 7.44-7.46 (m, 2H) 6.93 (d, J=7.02 Hz, 1H) 6.83 (d, J=8.85 Hz, 1H) 6.24 (d, J=6.71 Hz, 1H) 4.12 (s, 3H) 3.09 (s, 3H) 3.06 (d, J=7.32 Hz, 2H) 2.10-2.17 (m, 1H) 1.61-1.69 (m, 2H) 1.51-1.58 (m, 2H) 1.44-1.50 (m, 2H) 1.15-1.24 (m, 2H). MS (ESI+) m/z 400 (M+H)+.
