Vorschrift

In 30 ml of tetrahydrofuran was dissolved 2.7 g (4.26 mmol) of dibutyl[4-[2-[4-(tert-butyldiphenylsiloxymethyl)-2,5-dimethylphenyl]vinyl]-3-methoxyphenyl]amine, and 13.0 ml of tetrabutylammonium fluoride (1 mol solution in tetrahydrofuran) was added dropwise thereto with stirring at room temperature. The mixture was stirred for 3 hours. After the reaction mixture was poured into water, extraction with ethyl acetate, washing with a saturated saline solution, drying over anhydrous sodium sulfate, and concentration were performed. The residue was purified by silica gel column chromatography to give 1.57 g of a yellow liquid (yield: 93.5%).
