Reaction Steps

A mixture of 2-bromo-1-(cyclopropylmethoxy)-4-methanesulfonylbenzene (20.8 mg, 0.068 mmol), 2-methyl-6-(1-methylpyrazol-4-yl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)isoquinolin-1-one (30 mg, 0.08 mmol), NaHCO3 (14.28 mg, 0.17 mmol), and Pd(dppf)Cl2 (10 mg, 0.014 mmol) in dioxane (2.0 mL) and H2O (0.5 mL) was microwaved under N2 at 100° C. for 30 min. Purification by preparative HPLC gave the title compound (11 mg, 28%) as a white solid. 1H NMR (CDCl3, 400 MHz) δ 8.48 (d, J=8.4 Hz, 1H), 7.98-8.04 (m, 1H), 7.89 (d, J=2.4 Hz, 1H), 7.68 (s, 1H), 7.63 (s, 1H), 7.58-7.62 (m, 1H), 7.19-7.21 (m, 1H), 7.11-7.15 (m, 1H), 7.09 (s, 1H), 3.93 (s, 3H), 3.83-3.91 (m, 2H), 3.66 (s, 3H), 3.12 (s, 3H), 0.94-1.04 (m, 1H), 0.30-0.40 (m, 2H), 0.00-0.12 (m, 2H).
