Procedure

A mixture of 2-((2-bromopyridin-3-yl)methyl)-7-(4-(trifluoromethoxy)phenyl)phthalazin-1(2H)-one (25 mg, 0.053 mmol), cyclopropyl boronic acid (14 mg, 0.16 mmol), dppf(Pd)Cl2 (6 mg, 0.0079 mmol), potassium carbonate (29 mg, 0.021 mmol) in degassed dioxane (1 mL) was heated at 100° C. for 3 hours. The layers were separated, the organic layer was concentrated and the residue was purified by reverse phase HPLC to provide 2-((2-cyclopropylpyridin-3-yl)methyl)-7-(4-(trifluoromethoxy)phenyl)phthalazin-1(2H)-one as a white powder. C2-4H18F3N3O2. 438.1 (M+1).
