Participants

Reaction Steps

Then, 12.0 g of 1-(4,6-dimethoxy-2-methoxycarbonylmethoxy-3-isopentylphenyl)-3-(4-hydroxy-3-methoxyphenyl)-1-propanone was dissolved in 120 ml of methanol, and 70 ml of a 5% aqueous solution of potassium hydroxide was added to the solution and the mixture was stirred at room temperature for 20 minutes. Then, the reaction mixture was made weakly acidic by addition of dilute hydrochloric acid, and the solvent was removed by distillation and the residue was crystallized from ethyl acetate/diethyl ether/hexane to obtain 9.7 g (yield=85% of 1-(2-carboxymethoxy-4,6-dimethoxy-3-isopentylphenyl)-3-(4-hydroxy-3-methoxyphenyl)-1-propanone in the form of a white solid.
