実験手順
To a solution of 5-bromo-1-[1-(4-cyano-phenyl)-ethyl]-6-methyl-4-oxo-1,4-dihydro-pyridine-3-carboxylic acid methylamide (preparation 9, 100 mg, 0.267 mmol), 3-difluoromethyl-phenylboronic acid (67 mg, 0.390 mmol), palladium (0) tetrakis(triphenylphosphine) (25 mg, 0.022 mmol) in acetonitrile (2 mL) is added 2 M aqueous K2CO3 solution (0.30 mL, 0.60 mmol). After stirring for 18 h at 75° C., the reaction mixture is purified by preparative reversed-phase HPLC (XBridge, gradient of methanol in water, 0.1% NH4OH, 60° C.). Yield: 80 mg (71% of theory); ESI mass spectrum: [M+H]+=422; Retention time HPLC: 0.99 min (Z018_S04).
