実験手順
A mixture of 2-{[1-(phenylsulfonyl)-1H-indole-4-yl]oxy}ethylazide (3.3 g, 9.6 mmol) and triphenylphosphine (3.67 g, 14 mmol) in tetrahydrofuran and water is stirred under nitrogen for 24 hr at room temperature and filtered. The filtrate is concentrated in vacuo and the resultant residue is purified by flash chromatography (silica gel, EtOAc/MeOH/NH4OH: 8.5/1.5/0.05) to afford the title compound as an off-white solid, 2.54 g (80%), mp 71-73° C., identified by NMR and mass spectral analyses.
