反応手順
A solution of 16 mmol (3.3 g) of the 2-methylbutyl p-hydroxybenzoate obtained in 1.(2) in a solvent mixture of 20 ml of THF (tetrahydrofuran) and 40 ml of pyridine was cooled, and to the solution was added dropwise a THF solution of 10 mmol (2/9 g) of the 4-carbobenzoxyoxybenzoyl chloride obtained in 1.(4). The temperature was gradually returned to room temperature, and then the mixture was stirred for 8 hours. After conclusion of the reaction, the reaction solution and purified by column chromatography to obtain 2.9 g of 2-methylbutyl 4-(4'-carbobenzoxyoxybenzoyloxy)benzoate [m.p.: 64.4°-65.4° C⟧ (Yield: 63%)
