実験手順

A mixture of 6-[5-(4-bromo-phenyl)-1H-imidazol-2-yl]-4-oxo-hexahydro-pyrrolo[1,2-a]pyrazine-2-carboxylic acid methyl ester (65 mg, 0.15 mmol), [2-methyl-1-(2-{5-[4-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-phenyl]-1H-imidazol-2-yl}-pyrrolidine-1-carbonyl)-propyl]-carbamic acid methyl ester (77 mg, 0.15 mmol), tetrakis(triphenylphosphine)palladium(0) (18 mg, 0.015 mmol), potassium carbonate (42.8 mg, 0.31 mmol), 1,2-dimethoxyethane (4 mL) and water (1 mL) was heated in a microwave reactor at 120° C. for 20 minutes. The mixture was cooled and all volatiles were removed under reduced pressure. The resulting residue was taken up in dimethylformamide (2 mL) and subjected to reverse phase chromatography with an eluent of 0.1% TFA in water and 0.1% TFA in acetonitrile. The product-containing fractions were combined and the solvent was removed by lyophilization to provide 6-[5-(4′-{2-[1-(2-methoxycarbonylamino-3-methyl-butyryl)-pyrrolidin-2-yl]-3H-imidazol-4-yl}-biphenyl-4-yl)-1H-imidazol-2-yl]-4-oxo-hexahydro-pyrrolo[1,2-a]pyrazine-2-carboxylic acid methyl ester (16.8 mg, 0.024 mmol, 15%).
