Reaction Steps
A mixture of methyl 2-(2-benzyloxy-5-ethoxyphenyl)acetate (1.60 g), 5% palladium carbon (3.0 g) and tetrahydrofuran (50 mL) was subjected to catalytic hydrogenation at room temperature and 1 atm. After filtering off the catalyst, the solvent was evaporated under reduced pressure. Hexane was added to the obtained crystals and the mixture was filtrated to give crystals (0.82 g) of methyl 2-(2-hydroxy-5-ethoxyphenyl)acetate. Recrystallization from diisopropyl ether-hexane gave pale-yellow prism crystals. melting point: 83-84° C.
