Reaction Steps

To the said alcoholic substance, that is 1.42 g of 2-(4-pyridyl)-4-phenyl-2-butanol, 4 ml of 65% sulfuric acid was added and the mixture was stirred for two hours at 100° C. After cooling, water was added and the mixture was alkalized with sodium carbonate to extract with ethyl acetate. After drying over anhydrous sodium sulfate, the solvent was distilled away under reduced pressure to obtain viscous oily substance. The said oily substance was purified by silica gel column chromatography to obtain 0.44 g of (E)-1-phenyl-3-(4-pyridyl)-2-butene (yield: 33.7%) and 0.15 g of 4-phenyl-2-(4-pyridyl)-1-butene (yield: 11.5%).
