反応手順

20 ml of 10% hydrogen chloride-methanol was added to 1.94 g (10 mmol) of ferulic acid and the mixture was stirred at room temperature for one day. After the reaction mixture was concentrated under reduced pressure, the residue was dissolved in ethyl acetate, washed twice with water, and dried (MgSO4). The solvent was distilled off. The resulting residue was dissolved in 25 ml of methanol. 0.5 g of 10% palladium-carbon was added thereto and the solution was stirred overnight under hydrogen atmosphere. The reaction mixture was filtered and the filtrate was concentrated. The residue was purified by silica gel column chromatography (n-hexane:ethyl acetate=3:1 (v/v)) to obtain 1.86 g (8.85 mmol) of methyl 3-(4-hydroxy-3-methoxyphenyl)propionate as a colorless oily substance. Its spectroscopic data are as follows:
