Tetrabutylammonium Fluoride → HCID 24824075, compound

Participants

Reaction Steps

To a solution of [4-[2-[N-benzyl-N-[(2R)-2-[[tert-butyl(dimethyl)silyl]oxy]-2-(3-chlorophenyl)ethyl]amino]-ethyl]phenyl][4-[[tert-butyl(dimethyl)silyl]oxy]phenyl]-methanol (1.1 g) in tetrahydrofuran (15 ml) was added 1M tetrabutylammonium fluoride in tetrahydrofuran (5.0 ml) at 0° C., and the mixture was stirred at room temperature for 24 hours under nitrogen. The mixture was partitioned between ethyl acetate and water. The organic layer was separated, washed with water and brine, dried over magnesium sulfate and evaporated under reduced pressure. The residue was purified by column chromatography on silica gel (hexane/ethyl acetate=2/1) to give 4-[[4-[2-[N-benzyl-N-[(2R)-2-(3-chlorophenyl)-2-hydroxyethyl]amino]ethyl]-phenyl](hydroxy)methyl]phenol (550 mg).
