실험 절차

P(OEt)3 (0.9 mL, 903 mg, 5.4 mmol) was added to a solution of bromide 93 (904 mg, 3.6 mmol) in ethanol at 79° C. The resulting mixture was stirred at 79° C. for 4 h. The mixture was then cooled in an ice bath and NaOCl (19 mL of a 10-15% sol, 1.2 g, 16 mmol) was added. The solution was cooled and concentrated under reduced pressure to provided crude 94.
