Reaction Steps

2-Hydroxy-5-(t-butyloxycarbonylamino)pentanoic acid ethyl ester, (11, 26.1 g, 0.1 mol), triphenylphosphine (26.2 g, 0.10 mol), diethylazodicarboxylate (17.4 g, 0.1 mol), and diphenylphosphorylazide (27.5 g, 0.1 mol) is dissolved in THF (500 mL) and heated to reflux and maintained there for 8 hours. The reaction is cooled to room temperature, evaporated to an oil, and the product isolated by column chromatography using dichloromethane:ethanol as eluent.
