反応手順
A solution of octylbromide (4.19 g), 4-hydroxybenzoic acid (3 g) and potassium carbonate (3 g) in dimethylformamide (100 ml) was stirred at 130° C. for two hours. The solution was poured in water and neutralized with dilute aqueous hydrochloric acid solution. Diethylether was added to effect extraction. After the extracted layer was distilled to remove the solvent, the residue was added to a solution of sodium hydroxide (3.3 g), water (10 ml) and ethanol (50 ml). The solution obtained was refluxed for about a day and neutralized with dilute aqueous hydrochloric acid solution. The solution was distilled to remove the solvent and concentrated. The solid obtained was collected and recrystallized from water/ethanol to obtain the titled compound (3.88 g).
