Water → 3-Bromo-4-(methoxycarbonyl)benzoic acid

참여 물질

반응 단계

To a solution of dimethyl 2-bromoterephthalate (1.04 g) in methanol (10 mL) was added 1 N sodium hydroxide (5.71 mL) at room temperature. After stirring for 1.5 hour, the reaction was quenched by adding 1 N hydrochloric acid (7 mL). White crystals were formed. Water (10 mL) was added to aid crystalyzation. The crystals were collected by filtration, washed with water, and dried in the air. 3-Bromo-4-(methoxycarbonyl)benzoic acid was obtained as white crystals (532 mg).
