실험 절차

To a solution of 5-bromo-1-cyclobutyl-6-methyl-4-oxo-1,4-dihydro-pyridine-3-carboxylic acid (5-methyl-[1,3,4]oxadiazol-2-ylmethyl)-amide (preparation 24, 44 mg, 0.115 mmol), 3-(trifluoromethyl)phenyl-boronic acid (26 mg, 0.137 mmol), 1,1′-[bis(diphenylphosphino)ferrocene]dichloropalladium(II) (13 mg, 0.018 mmol) in acetonitrile (0.5 mL) is added 2 M aqueous K2CO3 solution (0.10 mL, 0.20 mmol). After stirring for 18 h at 75° C., the reaction mixture is filtered and purified by preparative reversed-phase HPLC (XBridge, gradient of methanol in water, 0.3% NH4OH, 60° C.). Yield: 40 mg (78% of theory); ESI mass spectrum: [M+H]+=447; Retention time HPLC: 1.09 min (Z003_001).
