Reaction Steps

4-Bromo-2-methyl-6-(4-methylpyrazol-1-yl)isoquinolin-1-one (40.0 mg, 0.126 mmol), the title compound of Example 90, step 1 (53.2 mg, 0.152 mmol), Pd(dppf)Cl2 (200.0 mg, 0.05 mmol) and aqueous 1M K3PO4 (0.38 mL, 0.38 mmol) in dioxane (3 mL) were heat in a microwave at 100° C. for 1 h. Purification by preparative HPLC gave the title compound (15.0 mg, 25%) as a white solid. 1H NMR (CDCl3, 400 MHz) δ 8.57 (d, J=8.4 Hz, 1H), 8.00 (d, J=8.4 Hz, 1H), 7.90 (s, 1H), 7.75 (d, J=7.6 Hz, 1H), 7.73 (s, 1H), 7.54 (s, 1H), 7.50 (s, 1H), 7.14 (s, 1H), 7.12 (s, J=9.2 Hz, 1H), 3.96-3.83 (m, 2H), 3.68 (s, 3H), 3.13 (s, 3H), 2.15 (s, 3H), 1.01-0.94 (m, 1H), 0.38-0.28 (m, 2H), 0.08-0.02 (m, 2H). LCMS: 464.1 (M+H)+.
