실험 절차

A mixture of 500 mg (3 mmol) of 4-hydroxy-3,5-dimethylbenzoic acid, 20 ml of absolute ethanol and a catalytic amount of anhydrous HCl was heated at reflux for 2 h. The mixture was then poured into excess cold water and the resultant precipitate was filtered. The precipitate was washed with water and dried in-vacuo to give the title compound as a white solid.
