実験手順
To the solution of methyl 4-(4-(tetrahydro-2H-pyran-2-yloxy)butan-2-yl)benzoate (501.8 mg 1.72 mmol) in methanol (60 mL) was added p-toluenesulfonic acid (592 mg, 3.44 mmol). the solution was stirred for 12 hours, then the solvent was remove and dissolved in dichloromethane (50 ml) and washed water, dried with sodium sulfate, concentrated to give methyl 4-(4-hydroxybutan-2-yl)benzoate (354 mg, 99%).
