反应详情

A THF solution of 0.1 mole of (S)-(+)-2-butanol and 0.1 mole of triethylamine was stirred at 0° C., and a THF solution of 0.12 mole of 4-carbobenzoxyoxybenzoic acid chloride was added dropwise. The temperature was returned to the room temperature slowly, and stirring was carried out for 8 hours. After the reaction, the reaction solution was ether extracted, dried, concentrated, and purified by column chromatography, to obtain 5.7 g of 4-carbobenzoxyoxybenzoic acid 1-methylpropyl ester. (yield: 18%)
