Procedure

A mixture of Example 7d (0.113 g, 0.2 mmol) and potassium carbonate (0.111 g, 0.800 mmol) in methanol (0.9 mL) and water (0.1 mL) was heated at 100° C. for 1 hour. The reaction was partitioned between ethyl acetate and water adjusting the pH to 7. The organic layer was separated, dried (Na2SO4), filtered and concentrated. The residue was purified by reverse phase HPLC (C18, 10-100% CH3CN/water (0.1% TFA)) to afford the title compound (0.012 g, 14%). 1H NMR (300 MHz, DMSO-d6) δ 2.99 (s, 3H) 3.27 (s, 3H) 3.51 (s, 3H) 6.27-6.32 (m, 1H) 6.93 (d, J=7.80 Hz, 2H) 6.99 (d, J=8.82 Hz, 1H) 7.03-7.10 (m, 1H) 7.25-7.34 (m, 4H) 7.40 (dd, J=8.65, 2.88 Hz, 1H) 7.55 (d, J=2.71 Hz, 1H) 12.01 (s, 1H).
