Versuchsvorschrift
1.41 g of 6-methoxy-7-(2-methoxyvinyl)quinoline was dissolved in 40 ml of 2 N hydrochloric acid-tetrahydrofuran (1:1), and the obtained mixture was then stirred at 70° C. for 2 hours. The reaction solution was cooled to a room temperature. It was diluted with ethyl acetate and then washed with a saturated sodium bicarbonate aqueous solution and a saturated sodium chloride aqueous solution. The organic layer was dried over magnesium sulfate and then concentrated under a reduced pressure, so as to obtain 1.45 g of (6-methoxyquinolin-7-yl)acetaldehyde containing triphenylphosphine oxide. This compound was used in the following reaction without further purification.
