Reaction Steps

A mixture of 2-(2-(4-bromo-1H-pyrazol-1-yl)ethyl)-7-(4-(trifluoromethoxy)phenyl)phthalazin-1(2H)-one (35 mg, 0.073 mmol), 2-methoxypyrimidin-5-ylboronic acid (13 mg, 0.087 mmol), dppf(Pd)Cl2 (2.7 mg, 0.0037 mmol), potassium carbonate (20 mg, 0.015 mmol) in degassed toluene (1 mL), degassed water (0.5 mL) and degassed isopropanol (0.5 mL) was heated at 85° 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-(4-(2-methoxypyrimidin-5-yl)-1H-pyrazol-1-yl)ethyl)-7-(4-(trifluoromethoxy)phenyl)phthalazin-1(2H)-one as a white powder. C25H19F3N6O3. 509.2 (M+1). 1H NMR (DMSO) δ 8.74 (s, 1H), 8.38-8.44 (m, 2H), 8.26 (dd, J=2.0, 8.0 Hz, 1H), 8.20 (s, 1H), 8.03 (d, J=8.4 Hz, 1H), 7.94 (d, J=8.8 Hz, 2H), 7.84 (s, 1H), 7.51 (d, J=8.4 Hz, 2H), 4.56 (s, 4H), 3.87 (s, 3H).
