実験手順

(2-Trifluoromethylphenyl)acetonitrile (3 g) and tetrabutylammonium bisulfate (550 mg) were suspended in toluene (30 mL), and a 50% sodium hydroxide aqueous solution (15 mL) was added dropwise under ice-cooling. After stirring for 10 minutes, (2-bromoethoxy)-tert-butyldimethylsilane (5.2 mL) was added at the same temperature. The mixture was brought back to room temperature and stirred overnight. Water was added to the reaction solution, followed by extraction with tert-butyl methyl ether. The resulting organic layer was washed with brine and then dried over anhydrous sodium sulfate. The drying agent was separated by filtration, and then the organic layer was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to obtain the title compound (5 g). The property values of the compound are as follows.
