实验过程
5-bromo-3-methyl-1H-pyridin-2-one (950 mg, 5.05 mmol), the title compound of Example 90, step 1 (2.93 g, 5.95 mmol), Pd(dppf)Cl2 (365 mg, 0.5 mmol) and K3PO4 (2.14 g, 10.1 mmol) in dioxane (30 mL) and water (5 mL) was purged with N2 and heated at 70° C. for 12 h. Silica gel chromatography (PE:DCM:EA=3:0:1 to 0:1:3) gave impure title compound (990 mg) as a yellow solid which was used directly in the next step. 1H NMR (CDCl3, 400 MHz) δ 12.57 (brs, 1H), 7.84 (d, J=8.8 Hz, 1H), 7.82 (s, 1H), 7.65 (s, 1H), 7.03 (d, J=8.8 Hz, 1H), 3.96 (d, J=7.2 Hz, 1H), 3.07 (s, 3H), 2.24 (s, 3H), 1.40-1.25 (m, 1H), 0.67-0.65 (m, 2H), 0.37-0.36 (m, 2H). LCMS: 334.1 (M+1)+
