반응 단계
Hydrogen chloride was bubbled into a stirred solution of 4-ethoxy-2-hydroxybenzoic acid (10.10 g, 0.554 mol) in methanol (2000 mL) until the solution was saturated. The solution was heated under reflux for 3 days and then cooled to 15° C. This caused the product to crystallize out. The crystals were collected, rinsed with methanol and hexanes, and dried. Methyl 4-ethoxy-2-hydroxybenzoate was obtained as a pale amber solid (49.3 g) melting at 77°-78° C.
