Procedure

The title compound of step 4 (200 mg, 0.627 mmol), the title compound of Example 90, step 1 (266 mg, 0.752 mmol), K3PO4 (400 mg, 1.881 mmol) and Pd(dppf)Cl2 (10 mg) in dioxane (4 mL) and H2O (1 mL) were heated at 70° C. for 18 h under N2. After preparative HPLC, the title compound (104.5 mg, 35.8%) was obtained as an off white solid. 1H NMR (CDCl3, 400 MHz) δ 9.64 (s, 1H), 8.24-8.18 (m, 2H), 8.07 (s, 1H), 7.96 (dd, J1=8.8 Hz, J2=2.4 Hz, 1H), 7.77 (s, 1H), 7.10 (d, J=8.8 Hz, 1H), 3.95 (s, 3H), 3.91 (d, J=7.2 Hz, 2H), 3.68 (s, 3H), 3.12 (s, 3H), 1.13-1.01 (m, 1H), 0.54-0.44 (m, 2H), 0.21-0.14 (m, 1H). LCMS: 466.1 (M+1)+
