To a solution of tert-butyl 2-(azidomethyl)-4-chlorobenzylcarbamate (10.9 g, 36.73 mmol) in THF (60 ml) and water (6 ml) was added triphenylphospine (10.59 g, 40.40 mmol). The reaction was heated to 65 C and stirred overnight at room temperature. The reaction was concentrated in vacuo and flashed with 4% (10% NH4OH/MeOH)/dichlor-omethane. A second purification using silica gel column chromatography with a careful gradient of 3 to 5% (10% NH4OH/MeOH)/dichloro methane gave the title compound.
