Methyl 3-t-butyl-4-hydroxy-5-iodobenzoate (2.77 g) was dissolved in N,N-dimethylformamide (50 mL), and potassium carbonate (12.0 g) and dimethylsulfuric acid (4.1 mL) were added to the solution, and then the mixture was stirred at room temperature for 16 hours. Water was added to the reaction solution, and then the reaction mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and then dried over anhydrous sodium sulfate. The solvent was distilled off under reduced pressure to obtain the title compound (2.77 g) as a brown crystal.
