Versuchsvorschrift
After 3-(4-hydroxy-phenyl)propionic acid (3 g, 18 mmol) was added with MeOH (6 mL), 4M HCl/dioxane solution (18 mL, 72 mmol) was added thereto, and the mixture was stirred at room temperature for 3 hours. The reactant was concentrated, added with EtOAc, and then washed with NaCl aqueous solution. The organic layer was separated, dried with MgSO4, and filtered to obtain the title compound (3.26 g, 99%).
