実験手順

Methyl 4-[2-(3-benzyloxy-2-pyridyl)ethenyl]benzoate (2.0 g, 5.8 nnol) was partially dissolved in EtOAc (20 ml) and EtOH (10 ml). The reaction vessel was flushed with argon, palladium-on-carbon (0.2 g, 10%) was added and the reaction was flushed with argon followed by hydrogen. The reaction was stirred at ambient temperature for 18 hours, filtered and evaporated to give methyl 4-[2-(3-hydroxy-2-pyridyl)ethyl]benzoate as a pale orange solid (1.3 g, 90%) which was used without further purification.
