Procedure

220 g of 4-methylpyridine and 1.0 g of solid base G were fed into a 1000 ml autoclave equipped with an electromagnetic stirrer under an atmosphere of nitrogen, and then heated to 140° C. with stirring at 700 r.p.m. Subsequently, 16.5 g of butadiene was added to the mixture in 1 hour. After the reaction, the autoclave was cooled and the catalyst was removed by filtration. The reaction solution was analyzed by gas chromatography. 4-(3-pentenyl)pyridine was obtained in a 83% yield based on 4-methypyridine consumed.
