Reaction Steps

For 5 min, N2 was bubbled through a mixture of 4-bromo-2-methyl-6-pyridin-2-ylisoquinolin-1-one (48.1 mg, 0.153 mmol), [3-(ethylsulfonylamino)phenyl]boronic acid (35.0 mg, 0.153 mmol), Pd(dppf)Cl2 (22.3 mg, 0.03 mmol) and aqueous 1M K3PO4 (0.38 mL, 0.38 mmol, 1 M) in dioxane (5 mL) which was then microwaved at 80° C. for 20 min. Purification by silica gel chromatography (PE:EA=3:1 to 1:2) followed by preparative HPLC gave the title compound (2.5 mg, 3.9%) as a white solid. 1H NMR (Methanol-d4, 400 MHz) δ 8.69 (d, J=8.4 Hz, 1H), 8.59 (d, J=8.4 Hz, 1H), 8.23 (d, J=1.2 Hz, 1H), 8.15-8.22 (m, 1H), 8.10 (dd, J1=8.4 Hz, J2=1.6 Hz, 2H), 7.65-7.62 (m, 1H), 7.50-7.45 (m, 3H), 7.38-7.30 (m, 2H), 3.71 (s, 3H), 3.16 (q, J=7.2 Hz, 2H), 1.32 (t, J=7.2 Hz, 3H). LCMS: 420.1 (M+H)+
