Reaction Steps
To a solution of (5-Fluoro-2-nitrophenyl) methanol (0.3 g, 1.75 mmol) in methylene chloride (5 mL0 was added triphenylphosphine (0.52 g, 2.01 mmol) and carbon tetrabromide (0.66 g, 2.01 mmol). After 3 hours, the reaction was concentrated and chromatographed using 3:1 hexane:ethyl acetate as eluant to provide 0.38 g (93%) of the desired product as white crystals. mp 38-41° C. Anal Calc'd for C7H5N3O2FBr: C, 35.93; H, 2.15; N, 5.99. Found: C, 35.97; H, 2.12; N, 5.91.
