Participants

Reaction Steps

To a solution of ethyl 3-(4-{[(4′-{[tert-butyl(dimethyl)silyl]oxy}-2′,6′-dimethylbiphenyl-3-yl)methyl][(2-nitrophenyl)sulfonyl]amino}-2-fluorophenyl)propanoate (6.32 g, 8.76 mmol) in tetrahydrofuran (60 mL) was added tetrabutylammonium fluoride (1 M solution, 9.64 mL, 9.64 mmol) under stirring at room temperature, and the mixture was stirred at room temperature for 2 hr. The reaction mixture was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane/ethyl acetate=10/1-hexane/ethyl acetate=1/1) to give the title compound (4.0 g, yield 75%) as colorless crystals.
