Sulfuric Acid → Methyl 3-Cyclopropyl-3-(3-hydroxyphenyl)propanoate

Participants

Reaction Steps

To a solution of 3-cyclopropyl-3-(3-hydroxyphenyl)propanoic acid (1.45 g) in methanol (20 mL) was added conc. sulfuric acid (75 μL), and the mixture was heated under reflux for 14 hr. Saturated aqueous sodium hydrogen carbonate solution was added to the reaction mixture at room temperature, and the mixture was extracted with ethyl acetate. The extract was washed with water and saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give a crude product of the title compound (1.43 g) as a pale-brown oil. This compound was used for the next step without further purification.
