Potassium trimethylsilanolate (purity: 90%)(250 g, 1,800 mmol) was added at room temperature to a solution of 100 g (450 mmol) of 1-bromo-4-(1-cyano-1-methylethyl)benzene (referential compound 1-1) in 1,000 ml of toluene with stirring in an argon stream and the mixture was stirred for 4.5 hours under a condition of heating to reflux. After the reaction was finished, the reaction solution was cooled down to room temperature and 500 ml of water was dropped thereinto. The mixed solution was stirred for 25 minutes at room temperature and the resulting solid was filtered off and washed with 400 ml of water to give 99 g of the title compound as white powder (yield: 92%).
