Reaktionsschritte
Isopropyl 3-fluoro-4-(1-methylethoxy)benzoate (618 mg, 2.57 mmol) was dissolved in methanol (13 mL). The resultant mixture was added with 1N aqueous solution of sodium hydroxide (13 mL) under ice-cold conditions and stirred at 60° C. for 1 hour. The reaction solution was added with a saturated solution of ammonium chloride and extracted with ethyl acetate. The organic layer was washed with brine, dried using anhydrous sodium sulfate, and concentrated in vacuo. 3-Fluoro-4-(1-methylethoxy)benzoic acid (505 mg, yield 99%) was obtained as a white crystal.
