A mixture of 3-(cyclopropylmethoxy)-2-iodo-6-methylsulfonylpyridine (140.0 mg, 0.40 mmol), 2-methyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)isoquinolin-1-one (136.5 mg, 0.48 mmol), K3PO4 (252.7 mg, 1.19 mmol) and Pd(dppf)Cl2 (29.2 mg, 0.04 mmol) in dioxane (5 mL) and H2O (1 mL) was stirred at 70° C. for 18 hrs under N2. The mixture was filtered and concentrated. The residue was purified by prep-HPLC to give the title compound (81.0 mg, 53.1%). 1H NMR (CDCl3, 400 MHz) δ 8.33 (dd, J1=8.4 Hz, J2=1.2 Hz, 1H), 8.07 (d, J=8.4 Hz, 1H), 7.83 (d, J=8.8 Hz, 1H), 7.74 (s, 1H), 7.67 (t, J=8.4 Hz, 1H), 7.55 (t, J=8.4 Hz, 1H), 7.39 (d, J=8.0 Hz, 1H), 4.01 (d, J=6.8 Hz, 2H), 3.60 (s, 3H), 3.25 (s, 3H), 1.10-0.98 (m, 1H), 0.45-0.37 (m, 2H), 0.23-0.17 (m, 2H). LCMS: 385.1 (M+1)+
