Participants

Reaction Steps

To a flask were added 93 g of 2-picoline, 21 g of 2-vinylpyridine, 1 g of sodium and a trace of hydroquinone. The mixture was heated to 130 C under nitrogen for 2 hours. After cooling to 22 C, 200 ml of water were added and the mixture was extracted with 150 ml diethyl ether. After washing the diethyl ether layer twice with 100 ml of water, and twice with 50 ml of 10% sodium sulfite, the solvent was removed and the product was purified by vacuum distillation to give 7.5 g of a light yellow oil.
