Reaction Conditions

Reaction Steps

To a solution of (E)-3-(3-hydroxyphenyl)acrylic acid (15.0 g) in methanol (100 mL) was added sulfuric acid (2.0 mL), and the mixture was stirred at 70° C. for 15 hr. Water was added to the reaction mixture, and the mixture was extracted with ethyl acetate. The extract was washed with saturated brine, and dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to give the title compound (15.8 g) as white crystals. This compound was used for the next step without further purification.
