N,N,N-Tributylbutan-1-aminium fluoride--hydrogen fluoride (1/1/2) → HCID 59238323, compound

Participants

Reaction Steps

To a solution of (E)-[2-(3-{4-[1-(4-bromo-phenylcarbamoyl)-3-(tert-butyl-dimethyl-silanyloxy)-propyl]-phenyl}-acryloylamino)-phenyl]-carbamic acid tert-butyl ester (1.6 g, 2.26 mmol) in THF (40 mL) was added tetrabutylammonium dihydrogen trifluoride (1.36 g, 4.52 mmol). This mixture was stirred at room temperature overnight and then evaporated to remove THF. The mixture was dissolved in water and extracted with ethyl acetate (3×30 mL). The combined organic layer was washed with brine, dried with Na2SO4, filtered, and evaporated. The crude product was purified by column chromatography (CH2Cl2:EtOAc=10:1) to get yellow solid product. MS: calc'd 594 (MH+), exp 594 (MH+).
