Procedure
To 2 L of toluene solution containing 217 g (containing an amount corresponding to 790 mmol) of 4-bromo-2-(2-chloroethoxy)-1-methoxybenzene obtained in Reference example 7-(a) were added 780 ml of 50% aqueous solution of sodium hydroxide and 268 g (789 mmol) of tetrabutylammonium hydrogensulfate under ice-cooling, and the mixture was stirred at room temperature for 3 hours. After completion of the reaction, the reaction mixture was poured into water, the organic layer after separation was washed successively with water and then with a saturated aqueous solution of sodium chloride, dried over anhydrous magnesium sulfate and then concentrated under reduced pressure. The obtained concentrate was applied to distillation under reduced pressure (79 to 83° C./100 Pa) to obtain 122 g of the title compound as a colorless oil. (Yield: 68%)
