실험 절차

Silver trifluoroacetate (0.52 g, 2.35 mmol) was added to a solution of (5R)-3-(3-fluorophenyl)-5-[(4-methyl-1H-1,2,3-triazol-1-yl)methyl]-1,3-oxazolidin-2-one (Intermediate 14) (0.50 g, 1.81 mmol) in dichloromethane (15 ml). Iodine (0.55 g, 2.17 mmol) was added over 1.5 hours, and it was stirred overnight. After 16 hours, the solids were removed by filtration and additional silver trifluoroacetate (0.38 g, 1.72 mmol) and iodine (0.27 g, 1.06 mmol) were added. After and additional 24 hours, the reaction mixture was filtered. The filter cake was washed with methanol. The methanol filtrate was concentrated under vacuum to give 0.31 g of the title product.
