1-Butanol → 3-Butoxy-4-tert-butylphenyl tert-butyl carbonate

Participants

Reaction Steps

tert-Butyl 4-tert-butyl-3-hydroxyphenyl carbonate (1.5 g, 5.6 mmol), n-butanol (0.5 mL, 5.4 mmol), triphenylphosphine (1.3 g, 5.0 mmol) and diethyl azodicarboxylate (DEAD) (0.78 mL, 5.0 mmol) were treated in the same procedure described in Example 31(a). The crude residue was applied to a silica gel chromatography column and eluted with a volume mixture of hexane and ethyl acetate (19/1 to 9/1) to furnish 964 mg (66% yield) of the title compound as a colorless oil.
