Hydrochloric Acid → 2-(3-Bromophenyl)-2-hydroxypropanoic acid

Participants

Reaction Steps

To a solution of 2-(3-Bromo-phenyl)-2-hydroxy-propionic acid ethyl ester (1.87 g, 6.7 mmol) in methanol (10 mL) was added potassium hydroxide (50% in water, 2 mL) and the solution was stirred at room temperature for 15 minutes. Hydrochloric acid (1 N) was added to adjust the pH to 4. The resulting mixture was extracted with ethyl acetate (10 ml×3). The combined organic layers were dried over sodium sulfate, filtered, and concentrated to afford the crude 2-(3-bromo-phenyl)-2-hydroxy-propionic acid as a white solid (1.6 g, 97%). MS: m/z 245 (M+H+).
