実験手順

Diethylazodicarboxylate (8.7 g) was added dropwise to a solution of 5-norbornene-2-methanol (6.2 g, 0.05 mol), 4-iodophenol (11.0 g, 0.05 mol) and triphenylphosphine (13.1 g, 0.05 mol) in 100 mL of anhydrous tetrahydrofuran. After completion of the addition, the resulting solution was stirred for 18 h at room temperature. The solvent was removed under reduced pressure and the oily residue was extracted three times with hot hexane. Combined hexane extracts were evaporated under reduced pressure to give 8 (15.0 g, 97%) as a colorless oil.
