A stirred mixture of (5R)-3-(3-fluoro-4-iodophenyl)-5-(4-hydroxymethyl-1H-1,2,3-triazol-1-ylmethyl)-1,3-oxazolidin-2-one (14.7 g, 35.1 mmol) and carbon tetrabromide (12.16 g, 36.7 mmol) in dichloromethane (1 L) was treated at 0° C. with triphenylphosphine (12.34 g, 61.2 mmol). The reaction mixture was stirred for 30 minutes at 0° C. and then at room temperature overnight. The reaction mixture was applied onto a silica-gel column and eluted with hexanes:ethyl acetate (1:1) and then with ethyl acetate:methanol (95:5) to give a product that was further purified by recrystallization from ethyl acetate to give the title compound as a colorless solid (14 g).
