| Product | Methyl 2-(6-hydroxy-2,3-dihydrobenzofuran-3-yl)acetate | HCID 57345855 | — |
Reaction Steps
A mixture of (6-hydroxy-benzofuran-3-yl)-acetic acid methyl ester (5.00 g), 10% palladium on carbon (0.50 g), and methanol (50 mL) is shaken under hydrogen atmosphere (3 bar) at room temperature for 3 h. The catalyst is separated by filtration and the filtrate is concentrated. The residue is chromatographed on silica gel (cyclohexane/ethyl acetate 4:1→1:1) to give the racemic title compound. Mass spectrum (ESI+): m/z=209 [M+H]+.
