실험 절차

To 1-(1-benzyl-1H-imidazol-2-yl)-2-ethylbutan-1-ol (1.78 g, 6.88 mmol) in THF (50 mL) at 0° C. was added triphenylphosphine (2.71 g, 10.3 mmol), diethyl azodicarboxylate (1.62 mL, 10.3 mmol) and diphenylphosphorylazide (2.22 mL, 10.3 mmol). The reaction mixture was slowly warmed to room temperature and stirred for 18 h. The reaction mixture was diluted with EtOAc and extracted 2 times with 1N HCl. The aqueous layer was washed EtOAc, then basicified with saturated aqueous NaHCO3 and extracted twice with EtOAc. The organic layer was dried over MgSO4, filtered, and concentrated in vacuo. The resulting oil was purified by column chromatography (SiO2, 100% CHCl3, then MeOH/CHCl3/Et3N, 1:98.5:0.5) to yield a pure oil in 30% yield.
