| Chemical Properties | brown crystalline powder | | Synthesis | General procedure for the preparation of methyl 4-amino-3-bromobenzoate: methyl 4-aminobenzoate (17 g, 0.1 mol) was dissolved in chloroform (250 mL). N-bromosuccinimide (20 g, 0.1 mol) was added slowly at 0 °C and the reaction mixture was stirred continuously for 3 h at this temperature. After completion of the reaction, the solvent was removed by distillation. Ethyl acetate (100 mL) was added to the residue for dissolution. Subsequently, the mixture was washed with aqueous sodium chloride to remove water-soluble impurities. The organic layer was separated and dried with anhydrous magnesium sulfate. After filtration, the product was purified by recrystallization from hexane to give the final methyl 4-amino-3-bromobenzoate (24.3 g, 93% yield).
