Reaction Steps
A stirred mixture of 4-bromo-3-methylphenol (184.1 g) and aqueous NaOH (850 ml, 2M) at 20° C. is treated with acetic anhydride (136 ml) and stirred at room temperature for 1 h. The suspension is extracted with diethyl ether (3×300 ml) and the combined extracts are washed with aqueous NaOH (2×100 ml 2M), dried (Na2SO4) and filtered. The solvent is evaporated off under reduced pressure to yield the title compound as an oil.
