Versuchsvorschrift

Under a hydrogen atmosphere, a tetrahydrofuran suspension (45 ml) of benzyl 2′-{[(1R)-3-{[tert-butyl(diphenyl)silyl]oxy}-1-methylpropyl]oxy}-3-fluorobiphenyl-4-carboxylate (2.23 g) and 20% palladium hydroxide carbon (2.23 g) was stirred at room temperature overnight. The reaction solution was filtered through Celite, and washed with methanol, and the filtrate was concentrated under reduced pressure. The residue was dried to afford 2′-{[(1R)-3-{[tert-butyl(diphenyl)silyl]oxy}-1-methylpropyl]oxy}-3-fluorobiphenyl-4-carboxylic acid (1.31 g).
