실험 절차
An aqueous solution of NaOH (1 mol) and KI (0.05 mmol) was added to a solution of 4-hydroxybenzoic acid (0.5 mmol) and 400 mL EtOH solution under a nitrogen atmosphere and stirred. After stirring for 30 minutes, an EtOH solution including bromopropanol (0.55 mmol) was dropped thereinto, and then, reacted for 24 hours after elevating to 80° C. A solvent was removed from a reaction product and hydrochloric acid-treatment was carried out. A solid phase was isolated through filteration, and 4-(3-hydroxypropoxy)benzoic acid as a compound of Formula 4 was synthesized.
