Versuchsvorschrift

A mixture of 3-bromo-5-iodobenzoic acid (9.0 g) in methanol (40 mL) was treated with 1M HCl in diethyl ether (27.5 mL). The reaction was heated overnight at 40° C. The solvent was then removed in vacuo, and the residue dissolved in ethyl acetate. The organic solution was washed with saturated sodium bicarbonate, dried over anhydrous sodium sulfate, filtered and concentrated to afford 8.8 g (94%) of methyl 3-bromo-5-iodobenzoate.
