実験手順

In 10 ml of tetrahydrofuran was dissolved 1.2 g (1.71 mmol) of 5-[2-[2-benzyloxy-4-[butyl[4-(tert-butyldiphenylsiloxy) butyl]amino]phenyl]vinyl]thiophene-2-carboaldehyde. To this mixture, 7.6 ml of tetrabutylammonium fluoride (1 mol/L solution in tetrahydrofuran) (7.6 mmol) was added dropwise with stirring at room temperature. The mixture was stirred for 1.5 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 residual liquid was purified by silica gel column chromatography to give 554 mg of a red crystal (yield: 70.1%).
