Water → 8-(4'-Methylbiphenyl-4-ylmethylamino)adenosine

Participants

Reaction Steps

To a mixture of 8-(4-bromobenzylamino)adenosine (0.050 g), 4-methylphenylboronic acid (0.017 g), sodium carbonate (0.024 g), water (0.4 mL) and ethanol (2.2 mL) was added tetrakis-(triphenylphosphine)palladium(0) (0.006 g), and the resulting mixture was stirred under reflux for 22 hours. The reaction mixture was cooled to room temperature. After addition of dichloromethane/methanol (5/1, 35 mL), the insoluble material was filtered out. The filtrate was concentrated under reduced pressure. The residue was purified by preparative reverse phase column chromatography (Shiseido CAPCELL PAK C18MG80, 5 μm, 20×50 mm, flow rate 30 mL/minutes linear gradient, eluent: water/methanol=70/30-10/90) to give the title compound (0.022 g).
