Procedure

To a solution of the title compound from Step 6 (45 mg, 0.12 mmol) and 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)isoquinolin-1-one (50 mg, 0.16 mmol) in dioxane (2.5 mL) and H2O (0.5 mL) was added Pd(dppf)Cl2 (9 mg, 0.013 mmol) and K3PO4 (86 mg, 0.4 mmol) in one portion at r.t. under N2. The mixture was stirred for 12 hours at 90° C. under N2. Water (15 mL) was added and the mixture was extracted with DCM (30 mL×3). The combined organic phases were dried over Na2SO4, filtered, concentrated under reduced pressure. The residue was purified by prep-HPLC to give the title compound (16 mg, yield: 32%) as a white solid. 1H NMR (CDCl3, 400 MHz) δ 8.52 (d, J=7.6 Hz, 1H), 8.11 (d, J=8.8 Hz 1H), 7.61-7.56 (m, 1H), 7.53-7.49 (m, 1H), 7.42 (d, J=8.8 Hz 1H), 7.38 (s, 1H), 7.34 (d, J=7.6 Hz 1H), 3.92 (d, J=7.2 Hz 2H), 3.68 (s, 3H), 3.41 (q, J=6.8 Hz, 2H), 1.33 (t, 3H), 1.08-1.02 (m, 1H), 0.54-0.48 (m, 2H), 0.22-0.21 (m, 2H).
