实验过程
The title compound of step 3 (100 mg, 0.42 mmol), the title compound of Example 90, step 1 (147 mg, 0.42 mmol), Pd(dppf)Cl2 (62 mg, 0.08 mmol), K3PO4 (221 mg, 1.04 mmol) in dioxane (4 mL) and H2O (0.5 mL) was purged with N2 and heated at 100° C. for 18 h. Following CH2Cl2 extractive work up, silica gel chromatography (PE:EA=2:10:1) and preparative HPLC, the title compound (54.57 mg, yield: 34.2%) was obtained as a yellow solid. 1H NMR: (DMSO-d6, 400 MHz) δ: 9.54 (s, 1H), 9.30 (s, 1H), 8.18 (s, 1H), 7.93 (dd, J1=8.8 Hz, J2=2.4 Hz, 1H), 7.85 (d, J=2.4 Hz, 1H), 7.31 (d, J=8.8 Hz, 1H), 3.91 (d, J=6.8 Hz, 2H), 3.61 (s, 3H), 3.20 (s, 3H), 0.94-0.92 (m, 1H), 0.35-0.30 (m, 2H), 0.10-0.06 (m, 2H). LCMS: 386.0 (M+H)+
