To the solution of methyl 4-(1-isopropoxyethyl)benzoate (161 mg, 0.73 mol) in methanol and water (50 mL/10 mL) was added lithium hydroxide (50 mg, 2.1 mmol), the solution was stirred at room temperature for 12 hours. Then the solution was acidified by hydrogen chloride (1 N/mol) pH to 6, extracted with dichloromethane (50 mL*3), evaporated the solvent to give 4-(1-isopropoxyethyl)benzoic acid (137 mg, 90%)
