Versuchsvorschrift

To a solution of ethyl 3-(2-fluoro-4-{[4-(4-hydroxy-2,6-dimethylphenyl)-2,3-dihydro-1H-inden-1-yl][(2-nitrophenyl)sulfonyl]amino}phenyl)propanoate (1.00 g, 1.58 mmol), 2-(ethylthio)ethanol (0.219 mg, 2.06 mmol) and tributylphosphine (0.417 mg, 2.06 mmol) in tetrahydrofuran (25 mL) was added 1,1′-(azodicarbonyl)dipiperidine (0.520 g, 2.06 mmol) under stirring at room temperature, and the mixture was stirred for 16 hr. The reaction mixture was diluted with diisopropyl ether, the insoluble material was filtered off, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (10%-80% ethyl acetate/hexane) to give the title compound (1.06 g, yield 93%) as a colorless oil.
