참여 물질

반응 단계

100 g of florfenicol was suspended in 500 g of hexanoic anhydride in one liter round bottom flask equipped with an overhead stirrer and a drying tube. To this suspension was added 3 ml of perchloric acid, while stirring vigorously, with a pipette. A clear solution was obtained in a few minutes. Stirring was continued for another 3 hours during which the product, florfenicol hexanoate pro-drug was recrystallized. The solid product was filtered using Buckner funnel under vacuum, washed thoroughly with hexane. The product was finally recrystallized in ethanol and the recrystallized product was washed with hexane and dried to obtain around 117 g of solid florfenicol hexanoate.
