실험 절차

To a solution of 1.26 g (4.27 mmol) of the resulting compound (9) and 1.8 ml (24.8 mmol) of anhydrous triethylamine dissolved in 20 ml of tetrahydrofuran under argon atmosphere was added dropwise 5 ml of an tetrahydrofuran solution containing 0.38 ml (4.08 mmol) of acryloyl chloride. The whole was stirred at room temperature overnight, thereby a salt precipitated. After addition of water to the reaction mixture, the whole was extracted with diethyl ether. The extract was purified by silica gel column chromatography. The resulting pale yellow solid was recrystallized from methanol to obtain 1.01 g of 4-cyano-4'-(6-acryloxyhexyloxy)biphenyl (10) (yield: 67.7%).
