A solution of diphenylphosphonyl azide (143 mg, 0.52 mmol in THF (2 ml) was added over a period of 15 minutes to a solution of 4-(1-hydroxytridecyl)-2-triethylsilylfuran (200 mg, 0.52 mmol), triphenylphosphine (140 mg, 0.52 mmol) and diethyl azidocarboxylate (90 mg, 0.52 mmol) in THF (10 ml) at room temperature. After stirring for 2 days, the mixture was evaporated in the presence of a minimum amount of silica gel. The residue was purified by flash chromatography on silica using 5% ethyl ether/hexane to give the titled azide.
