Erythromycin → Flurithromycin

Participants

Reaction Steps

Erythromycin A (5 g, 6.813 mmole) was dissolved in glacial acetic acid (20 mL) at room temperature and stirred for 2 hours. N-fluorobenzenesulfonimide (2.2 g, 6.813 mmole) dissolved in THF (4 mL) was added and stirring continued for an additional 18 hours at 22° C. The reaction was worked up in the same manner as Example 1 to afford only 0.93 g (7% yield) of crude flurithromycin.
