Ethyl 2,4-dibromoorcinol-6-carboxylate

A solution of 140 g. (0.71 mole) of the above ester in 450 ml. of acetic acid is treated with a solution of 105 ml. of bromine in acetic acid, the temperature of the reaction mixture being held around 40° during this operation. The reaction mixture is stirred overnight, and the precipitated ethyl 2,4-dibromoorcinol-6-carboxylate is filtered and recrystallized from ethanol. The yield is 195 g.
