Reaction Steps
Then, 15.5 g of 1-(4,6-dimethoxy-2-methoxycarbonylmethoxy-3-isopentylphenyl)-3-(3-methoxy-4-methoxymethoxyphenyl)-1-propanone was dissolved in 25 ml of methanol, and 23 ml of hydrochloric acid/methanol was added to the solution and the mixture was heated and fluxed for 10 minutes. After the reaction, the solvent was removed by distillation, and the obtained solid was dissolved in a small amount of ethyl acetate and crystallized by diethyl ether/hexane to obtain 11.9 g (yield=84%) of 1-(4,6-dimethoxy-2-methoxycarbonylmethoxy-3-isopentylphenyl)-3-(4-hydroxy-3-methoxyphenyl)-1-propanone in the form of a white solid.
