Reaktionsschritte

250 g of florfenicol was suspended in 330 ml of acetic anhydride in one liter round bottom flask equipped with a over-head stirrer and a drying tube. To this suspension was added one ml of perchloric acid, while stirring vigorously with a pipette. A clear yellow solution was obtained in a few minutes. Stirring was continued for another 3 hours. After 3 hrs, the reaction mixture was poured into 1000 g of ice and stirring continued to arrive at a suspension of product. Solid present was filtered and resuspended in 500 ml of water, and then stirred for 10 min to remove residual acetic acid. The solid product was filtered using a Buckner funnel under vacuum and then recrystallized in ethanol. The recrystallized product was washed with hexane and dried to obtain around 260 g of solid florfenicol acetate.
