A mixture of 4-bromo-2-methylisoquinolin-1(2H)-one (100 mg, 0.42 mmol), and (3-methoxyphenyl)boronic acid (70 mg, 0.46 mmol), PPh3 (66 mg, 0.25 mmol), Na2CO3 (133 mg, 1.26 mmol), and Pd(dppf)Cl2 (62 mg, 0.084 mmol) in dioxane (2.5 mL) and water (0.5 mL) was heated overnight at 90° C. Extractive work up with ethyl acetate followed by preparative TLC (PE:EA=1:1) gave the title compound (18 mg, 0.07 mmol) as a white solid in 17% yield. 1H NMR (DMSO, 400 MHz): δ 8.30 (d, 1H, J=7.68), 7.68 (t, 1H, J=7.56), 7.50-7.55 (m, 3H), 7.40 (t, 1H, J=7.44), 6.97-7.00 (m, 3H), 3.78 (s, 3H), 3.54 (s, 3H). MS (m/z, relative intensity): 266 (M+, 1).
