Procedure
To a solution of benzyl (4-{[tert-butyl(dimethyl)silyl]oxy}-2-cyclopropylphenyl)acetate (586 mg) in tetrahydrofuran (6.89 mL) was added a 1 M solution of tetra-n-butylammonium fluoride in tetrahydrofuran (2.23 mL) under ice-cooling, followed by stirring at room temperature overnight. To a reaction solution was added water, followed by extraction with ethyl acetate. The organic layer was washed with water and a saturated aqueous sodium chloride solution in this order, then dried over anhydrous sodium sulfate, and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane-ethyl acetate) to obtain benzyl (2-cyclopropyl-4-hydroxyphenyl)acetate (398 mg).
