反応手順
To a solution of 3-(3-benzyl-4-hydroxy-phenyl)-2-ethoxy-propionic acid ethyl ester (0.38 g, 1.16 mmol) in MeOH (5 mL), a solution of KOH (1.62 g, 29 mmol) in H2O (5 mL) was added. The mixture was stirred for 2 h at room temperature then acidified with aq. HCl (10%) and extracted with dichloromethane. The combined organic layers were dried and evaporated and the remaining crude product was purified by column chromatography to yield the title compound as an oil (0.35 g, 74.8%). Mass Spectrum: M+H+ 300.94, M−H+ 298.99.
