Hydrochloric Acid → 4-(((1R)-2,2-difluorocyclopropyl)methoxy)benzoic Acid

Participants

Reaction Steps

A mixture of methyl 4-(((1R)-2,2-difluorocyclopropyl)methoxy)benzoate (637 mg), THF (10 mL), methanol (10 mL) and 1M aqueous sodium hydroxide solution (10 mL) was stirred at room temperature overnight. The reaction mixture was neutralized with 1M hydrochloric acid at 0° C., and the mixture was extracted with ethyl acetate. The combined organic layer were washed with saturated brine, and dried over anhydrous magnesium sulfate, and the solvent was evaporated under reduced pressure to give the title compound (559 mg).
