反応手順

To a methylene chliride (3 ml) solution of tert-butyl (4-tert-butyl-3-chlorophenoxy)acetate (820 mg, 2.4 mmol) was added trifluoroacetic acid (TFA) (3 ml). The mixture was stirred for 5 hours at ambient temperature. The solvent was removed under reduced pressure to give a residue, which was applied to a recrystallization from hexane-methylene dichloride to furnish 657 mg (100% yield) of the title compound as a white solid.
