Procedure

Di-isopropylazodicarboxylate (1.3 mL, 6.6 mmol) was added dropwise to a solution of 2-nitroimidazole (1.0 g, 9 mmol), N-trityl-L-serine methyl ester (2.0 g, 6 mmol) and triphenylphosphine (1.73 g, 6.6 mmol) in THF (100 mL). The reaction was stirred at ambient temperature for approximately 5 hours The volatiles were removed by evaporation under reduced pressure and the residue purified by column chromatography (EtOAc:isohexane 1:19) to afford the title compound (1.2 g, 44%) as a white solid.
