Reaction Steps

A mixture of the title compound from Step 6 (105 mg, 0.315 mmol), 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)isoquinolin-1-one (108 mg, 0.379 mmol), K2CO3 (131 mg, 0.949 mmol) and Pd(dppf)Cl2 (23.1 mg, 0.032 mmol) in dioxane/H2O (10 mL/3 mL) was heated to 85° C. for 2 h. It was then filtered and extracted with EtOAc. The organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (PE/EA 50:1 to 20:1 to 10:1) to give the title compound (25 mg, 19%). 1H NMR (400 MHz, CD3OD) δ 8.31 (d, J=8.4 Hz, 1H), 7.59-7.55 (m, 1H), 7.47-7.43 (m, 1H), 7.31-7.23 (m, 2H), 7.05 (s, 1H), 6.95 (d, J=2.8 Hz, 1H), 3.77-3.71 (m, 1H), 3.60 (s, 3H), 2.95-2.75 (m, 5H), 1.95-1.92 (m, 1H), 1.66-1.54 (m, 1H), 1.38-1.22 (m, 2H), 0.59-0.55 (m, 1.25H), 0.42-0.38 (m, 1.75H). LCMS: 413.0 (M+1)+.
