Reaction Steps
To a solution of methyl (6-hydroxy-1-benzofuran-3-yl)acetate (11.4 g, 55.3 mmol) in methanol (100 mL) was added 10% palladium on carbon (50% water wet, 2 g), and the mixture was stirred under hydrogen atmosphere (balloon pressure) at room temperature for 18 hr. The catalyst was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (20%-50% ethyl acetate/hexane), and the obtained solid was recrystallized from ethyl acetate-hexane to give the title compound (8.74 g, yield 76%) as colorless prism crystals.
