実験手順

2-(Tributylstannyl)furan (472 μL, 1.5 mmol) was added to a DMF (2.5 mL) solution containing 1-(2-deoxy-β-D-ribofuranosyl)-4-iodo-2-nitropyrrole (177 mg, 0.5 mmol) and bis(triphenylphosphine)palladium(II) dichloride (18 mg, 0.025 mmol). The mixture was reacted at 100° C. for 30 minutes in a microwave machine (standard mode). The reaction solution was separated between ethyl acetate (50 mL) and water (50 mL). The organic layer was concentrated and purified by HPLC to yield 1-(2-deoxy-β-D-ribofuranosyl)-4-(furan-2-yl)-2-nitropyrrole (111 mg, 0.38 mmol, 76%).
