Pyridine, hydrofluoride (1:1) → HCID 53861240, compound

Participants

Reaction Steps

To a solution of 1,2-epoxy-2-(N,N-diphenylcarbamoyloxymethyl)-5-ethoxycarbonylmethyloxy-1,2,3,4-tetrahydronaphthalene (0.2 g) in CH2Cl2 (30 ml) was added HF-pyridine (0.5 ml) at 0° C. After being stirred for 2 hours, the solvent was removed in vacuo. The residue was extracted with ethyl acetate. The mixture was washed with 1N--HCl solution, sat. NaHCO3, and brine, dried over MgSO4, and evaporated in vacuo. The residue was purified by chromatography on silica gel to afford 1-fluoro-2-hydroxy-2-(N,N-diphenylcarbamoyloxymethyl)-5-ethoxycarbonylmethyloxy-1,2,3,4-tetrahydronaphthalene (70 mg)
