6-(4-Bromo-thiophen-2-yl)-1-(2,4-difluoro-benzyl)-2-oxo-4-trifluoromethyl-1,2-dihydro-pyridine-3-carbonitrile 620 mg, 1.3 mmoles), [3-(4,4,5,5-Tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-acetic acid methyl ester (520 mg, 1.95 mmoles), [1,1′-bis(diphenylphosphino)ferrocene]-dichloropalladium(II) complex with DCM (1:1) (32 mg, 0.39 mmoles), and K2CO3 (540 mg, 3.91 mmoles) were combined in 6 ml of DME/H2O (9:1, degassed), and were stirred at 85° C. for 5 hours. After this period the reaction mix was evaporated and purified using flash silica chromatography (0-30% EtOAc/Hexane) to yield (3-{5-[5-cyano-1-(2,4-difluoro-benzyl)-6-oxo-4-trifluoromethyl-1,6-dihydro-pyridin-2-yl]-thiophen-3-yl}-phenyl)-acetic acid methyl ester (365 mg, 52%) as a yellow solid. 1H-NMR (CDCl3): δ 7.64 (br d, J=1.3 Hz, 1H), 7.39-7.35 (m, 2H), 7.33 (br d, J=1.3 Hz, 1H), 7.14-7.07 (m, 1H), 6.92-6.85 (m, 1H), 6.84-6.77 (m, 1H), 6.65 (s, 1H), 5.44 (s, 2H), 3.72 (s, 3H), 3.67 (s, 2H). MS (ES+): 545.3 (M+H).
