Versuchsvorschrift

To a solution of [4-(diphenylmethoxy)-3-isobutylphenyl]methanol (0.49 g, 1.41 mmol), ethyl 3-(2-fluoro-4-{[(2-nitrophenyl)sulfonyl]amino}phenyl)propanoate (0.62 g, 1.56 mmol) and triphenylphosphine (0.55 g, 2.10 mmol) in tetrahydrofuran (25 mL) was added diethyl azodicarboxylate (40% toluene solution, 0.93 mL, 2.13 mmol) at room temperature, and the mixture was stirred at room temperature for 18 hr. The reaction mixture was concentrated, and the residue was subjected to silica gel column chromatography (ethyl acetate/hexane=3/97-15/85) to give the title compound (800 mg, yield 78%) as a colorless oil.
