2-Cyclohexenol (491 mg, 0.49 ml, 5.00 mmol, 1.0 equiv.), 2-acetamidophenol (756 mg, 5.00 mmol, 1.0 equiv.) and triphenylphosphine (1.44 g, 5.50 mmol, 1.1 equiv.) were dissolved in THF (10 ml) and kept at ambient temperature by a water bath. After dropwise addition of diethyl azodicarbonic acid (871 mg, 0.78 ml, 5.00 mmol, 1.0 equiv.), dissolved in THF (3 ml), the reaction mixture was stirred over night. Extractive work-up and flash chromatography on silica gel (heptane/tertbutyl(methyl)ether=1:1) afforded 224 mg (19%) the title compound as a yellow oil.
