Procedure

A solution of 2-(2,3-dihydrobenzo[1,4]dioxin-5-yloxy)ethylazide (3.43 g, 0.016 mol) and triphenylphosphine (6.3 g, 0.023 mol) in tetrahydrofuran (50 ml) and water (2 ml) was allowed to stir for 18 hours at room temperature. The solvent was removed under vacuum. Chromatography (30% methanol-methylene chloride plus ammonium hydroxide) afford 1.93 g (62%) of product as a yellow oil. MS FAB m/e 196 (M+H)+
