Procedure

A solution of 2-(6-fluorochroman-8-yloxy)ethylazide (4.12 g, 0.017 mol) and triphenylphosphine (6.83 g, 0.026 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) removed triphenylphosphine and triphenylphosphine oxide (40% methanol-methylene chloride plus ammonium hydroxide) to afford 3.45 g (94%) of product as a white solid: mp 68-70° C.
