実験手順

Potassium carbonate (453 g) and methyl iodide (164 ml) were added to a solution of 4-bromo-2-(tert-butyl)-6-nitrophenol (600 g) in dimethylformamide (6000 ml) and the mixture was stirred at 50° C. for 4 hours. Ether (6000 ml) was added and the reaction mixture was washed 3 times with water. The organic layer was dried over anhydrous magnesium sulfate and the solvent was distilled off under reduced pressure to yield a crude product of the title compound (569 g) as a yellow oil.
