Hydrochloric Acid → HCID 14368083, compound

Participants

Reaction Steps

Then, 20.6 g of 1-(2-hydroxy-4-methoxy-3-isopentylphenyl)-3-(4-methoxycarbonylmethoxyphenyl)-1-propanone was dissolved in 100 ml of methanol, and 100 ml of a 5% aqueous solution of potassium hydroxide was added to the solution and the mixture was stirred at room temperature for 1 hour. After the reaction, the reaction mixture was made acidic by dilute hydrochloric acid, and the formed precipitate was recovered by filtration and recrystallized from benzene to obtain 15.2 g (yield=96.8%) of 1-(2-hydroxy-4-methoxy-3-isopentylphenyl)-3-(4-carboxymethoxyphenyl)-1-propanone in the form of a colorless grain.
