Reaction Steps

To the said oily substance, that is , 8.83 g (36.6 mmol) of 2-phenyl-4-(4-pyridyl)-2-pentanol, 15 ml of 65% sulfuric acid was added and the mixture was heated for 2 hours at 100° C and after cooling, water was added. The mixture was alkalized with sodium carbonate and was extracted with ethyl acetate. Subsequently, layer a of ethyl acetate was dried over anhydrous sodium sulfate and the solvent was distilled away under reduced pressure and purified by silica gel column chromatography to obtain 0.45 g of (E)-2-phenyl-4-(4-pyridyl)-2-pentene (yield: 17%) and 0.10 g of (Z)-2-phenyl-4-(4-pyridyl)-2-pentene (yield: 4%).
