4-[3-Amino-1-(3-bromophenyl)-1H-isoindol-1-yl]benzonitrile (0.086 g, 0.22 mmol) (Example 50), (2-fluoropyridin-3-yl)boronic acid (0.047 g, 0.33 mmol), [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) chloride dichloromethane adduct (0.018 g, 0.022 mmol), potassium carbonate (0.091 g, 0.66 mmol) and solvent (3 mL of a mixture of dimethoxyethene, water and ethanol in a ratio of 6:3:1) was irradiated under argon atmosphere in a microwave at 125° C. for 6 min. When cooled to ambient temperature the mixture was partitioned between ethyl acetate and water; the organic phase was dried over magnesium sulfate and evaporated. Purification by preparative HPLC to give 0.062 g (70% yield) of the title compound. 1H NMR (DMSO-d6) δ 8.22 (dd, J=3.28, 1.52 Hz, 1 H), 8.05-7.94 (m, 1 H), 7.84-7.75 (m, 2 H), 7.75-7.69 (m, 2 H), 7.56-7.34 (m, 9 H), 6.90 (br s, 2 H); MS (AP) m/z 405 [M+1]+.
