实验步骤: In 200 ml of N,N-dimethylformamide were dissolved with heating 20 g of 4-hydroxyphthalonitrile and 10.55 g of potassium carbonate, to which 20 g of chloroethyl-trimethylsilane were added dropwise at 40° C. in the atmosphere of argon. Immediately after the addition, the mixture was stirred for 18 hours while maintaining the reaction temperature at 85°-105° C. The reaction vessel was then cooled to room temperature and 250 ml of dilute hydrochloric acid was added. The mixture was extracted with 1.2 liters of toluene. The organic layer was washed well with water and water was removed with magnesium sulfate. Thereafter, toluene was removed by distillation and the residue was purified with a toluene/silica gel column to obtain 24.6 g (yield: 77.0%) of a compound having the formula (XVII) below. ##STR39## Immediately after the addition while maintaining the reaction temperature at 85°-105° C The mixture was extracted with 1.2 liters of toluene The organic layer was washed well with water and water was removed with magnesium sulfate Thereafter, toluene was removed by distillation the residue was purified with a toluene/silica gel column
