실험 절차

A solution of 1,1-dimethylethyl (3S)-3-{[4-(4-bromophenyl)-5-oxo-4,5-dihydro-1H-1,2,4-triazol-3-yl]methyl}-1-pyrrolidinecarboxylate (1.181 mmol) in dioxane (6 mL) was treated with 7-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)quinoline (1.215 mmol), dichloro[1,1′-bis(diphenylphosphino)ferrocene]palladium(II)-dichloromethane adduct (50 mg), and 2M aq potassium carbonate (3 mL). The reaction mixture was purged with nitrogen, sealed, and stirred at 110° C. for 1 h. The solution was cooled to room temperature and the dioxane layer separated from the aqueous layer. The dioxane layer was removed via pipette and was passed through a plug of celite and sodium sulfate. The plug was washed with dioxane (6 mL). All dioxane filtrates were combined and concentrated in vacuo. Silica gel chromatography (0-20% methanol:ethyl acetate) was utilized in purifying the title compound (386 mg, 69%). MS(ES)+ m/e 472.2 [M+H]+.
