Reaction Steps

(R)-4-(6-Hydroxynaphthalen-2-yl)-4-methyloxazolidin-2-one (Example 4, 5.05 g, 20.8 mmol) was suspended in acetonitrile (50 mL, 1000 mmol) in a capped 200 mL round-bottom flask equipped with a magnetic stir bar. The mixture was cooled to 0° C. and N-bromosuccinimide (3.88 g, 21.8 mmol) was added. The reaction mixture was stirred for 1 hour. HPLC analysis indicated that the reaction was complete. The mixture was filtered. The residue was rinsed with acetonitrile, air dried under vacuum and collected (5.54 g). The crude product required no purification (82% yield).
