To a mixture of N-(7-bromoisoquinolin-3-yl)cyclopropanecarboxamide (121.6 mg, 0.4177 mmol, 2-methyl-1-propenylboronic acid pinacol ester (129 uL, 0.629 mmol), bis(di-tert-butyl(4-dimethylaminophenyl)phosphine)dichloropalladium(II) (15.9 mg, 0.0224 mmol), and potassium carbonate (150.5 mg, 1.089 mmol) was added 1,4-dioxane (2 mL, 20 mmol) and water (0.2 mL, 10 mmol). The reaction mixture was stirred at 90° C. for 3 hours. The reaction mixture was then poured into ethyl acetate, which was washed with two portions water, dried with brine and MgSO4, filtered, and evaporated in vacuo to yield 144.5 mg of crude product. 44 mg of this crude material was purified via reverse phase HPLC and lyophilized to yield 28.2 mg N-(7-(2-methylprop-1-enyl)isoquinolin-3-yl)cyclopropanecarboxamide.
