실험 절차

Into a round bottom flask, there are introduced 2.86 g (10 mmoles) of 3-(1-adamantyl)-4-methoxybenzoic acid, 1.73 g (10 mmoles) of 4-hydroxybenzenesulfonamide and 50 ml of THF. There are added, successively, 2.1 g (10 mmoles) of 1,3-dicyclohexylcarbodiimide and then 1.22 (10 mmoles) of 4-dimethylaminopyridine. The medium is stirred at ambient temperature for 4 hours. The reaction medium is poured into water and extracted with ethyl ether. The organic phase is decanted, washed with water, dried on magnesium sulfate and evaporated. The resulting solid is purified by chromatography on a silica column eluted by a 60:40 mixture of ethyl ether and hexane. After evaporation of the solvents, 2 g (46% yield) of 4-[3-(1-adamantyl)-4-methoxybenzoyloxy] benzenesulfonamide having a melting point of 223°-224° C. are recovered.
