A solution of 2-(5-fluoro-2-methoxy-phenoxy)ethylazide (3.97 g, 0.019 mol) and triphenylphosphine (5.95 g, 0.023 mol) in tetrahydrofuran (80 ml) and water (1.5 ml) was allowed to stir for 18 hours at room temperature. The solvent was removed under vacuum. Chromatography (ethyl acetate followed by 25-50% methanol-ethyl acetate plus ammonium hydroxide) removed triphenylphosphine and triphenylphosphine oxide and afforded 3.14 g (90%) of product as a clear oil. MS EI m/e 185 (M+)
