실험 절차

2 g 4-Hydroxy-3-trifluoromethyl-benzonitrile, 5.6 g triphenylphosphine and 1.2 g tetrahydro-4H-pyran-4-ol was suspended in 15 mL tetrahydrofuran at 0° C. before 4.92 g di-tert-butylazodicarboxylate (DBAD) as a solution in 5 mL tetrahydrofuran was added over 15 min. The reaction was warmed to ambient temperature. Additional 2.8 g triphenylphosphine, 0.55 g (5.3 mmol) tetrahydro-4H-pyran-4-ol and 2.46 g di-tert-butylazodicarboxylate (DBAD) in tetrahydrofuran were added and the reaction was stirred overnight. After this time, the reaction was diluted with water and extracted with ethyl acetate (×2). The organic phase was separated and then it was washed with 2N sodium hydroxide, water and saturated sodium chloride, dried over sodium sulfate, filtered and the filtrate was concentrated under reduced pressure. The residue was purified with silica gel chromatography (SiO2: heptane/ethyl acetate) to provide the title compound.
