A mixture of 1-(3-bromophenyl)-1-pyridin-4-yl-1H-isoindol-3-amine (Scheme #9, C) (0.073 g, 0.20 mmol), 3-fluoro-5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine (0.067 g, 0.30 mmol), potassium carbonate (0.055 g, 0.40 mmol), [1,1′-bis(diphenylphosphino)ferrocene]palladium(II) chloride dichloromethane adduct (0.020 g, 0.025 mmol), dimethoxyethane (2 mL), water (1 mL) and ethanol (0.3 mL) under an argon atmosphere was irradiated in a microwave at 100° C. for 15 min. The reaction mixture was filtered and partitioned between water and ethyl acetate, the organic phase was concentrated and the residue was purified by preparative HPLC, which gave the title compound (0.041 g, 54%). 1H NMR (DMSO-d6) δ 8.67-8.63 (m, 1 H), 8.57 (d, J=2.78 Hz, 1 H), 8.49-8.42 (m, 2 H), 7.99-7.90 (m, 2 H), 7.85-7.79 (m, 1 H), 7.67-7.62 (m, 2 H), 7.55-7.41 (m, 4 H), 7.37-7.28 (m, 2 H), 6.95 (br s, 2 H), 1.91 (s, 2.2 H); MS (ESI) m/z 381 [M+1]+.
