실험 절차

(3-Benzyloxy-4-chloro-phenyl)-acetic acid (8 g) was treated with hydrogen chloride (4N in 1,4-dioxane; 6 mL) in EtOH (100 mL) at 80° C. for 3 hours. After concentrating to dryness, the residue was purified by silica gel chromatography to give (3-benzyloxy-4-chloro-phenyl)-acetic acid ethyl ester.
