Reaction Steps
Methyl 4-hydroxybenzoate (25.00 g) was dissolved in chloroform (225 mL) and methanol (25 mL), and a chloroform (30 mL) solution of bromine (8.5 mL) was added dropwise to the solution, and then the mixture was stirred for 2 hours. The reaction solution was diluted with chloroform, washed with water, an aqueous 10% sodium thiosulfate solution and saturated brine and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain the title compound (37.81 g) as a colorless crystal.
