Reaction Steps

With reference to the document (J. Org. Chem., (2002), 67, 1093-1101), potassium carbonate (83.0 g, 600 mmol) was added to a solution of DMF (500 mL) containing 4-bromophenol (50.4 g, 291 mmol) at room temperature. The mixture was stirred at the same temperature for 30 minutes, and then 2-chloroethyl 4-methylbenzenesulfonate (70.2 g, 299 mmol) was added thereto. The mixture was stirred at 50° C. for 24 hours. The reaction solution was cooled to 10° C., and water (500 mL) was added thereto to precipitate a white solid. This white solid was collected by filtration, washed with water (500 mL), and dried at 50° C. under reduced pressure to give 58.6 g of the title compound (yield: 86%).
