反応手順

To a solution of p-hydroxybenzoic acid (3 g) and triethylamine (2.4 g) in dichloromethane (30 ml) were added undecanoyl chloride (4.5 g) and dimethylaminopyridine (0.2 g). The mixture was stirred at room temperature for about 20 hours. After dilute aqueous hydrochloric acid solution was added, an organic layer was separated by a funnel. After the solution was distilled to remove the solvent, the residue was washed with n-hexane and dried to obtain the titled compound (about 5 g).
