実験手順

850 mg (1.9 mmol) of ethyl 3″-tert-butyl-4″-diethylamino-4′-hydroxy[1,1′;3′,1″]terphenyl-4-carboxylate (obtained in Example 1d) are dissolved in dimethylformamide under nitrogen. 92 mg (2.3 mmol) of 60% sodium hydride are added. After 20 minutes at room temperature, 0.25 mL (2.3 mmol) of 2-bromoethan-1-ol acetate are added and the mixture is stirred for 24 hours at room temperature and then poured into saturated ammonium chloride solution and extracted with ethyl acetate. The organic phase is washed with water and then dried and evaporated. The residue obtained is purified by chromatography on silica gel (eluent: 70/30 heptane/ethyl acetate). 1 g of ethyl 4′-(2-acetoxyethoxy)-3″-tert-butyl-4″-diethylamino[1,1′;3′,1″]terphenyl-4-carboxylate is obtained (yield=99%) in the form of a colorless oil.
