4-Methylpyridine → Dimethyl-(2-pyridin-4-yl-vinyl)-amine

Participants

Reaction Steps

A solution of 47 g 4-picoline and 105.5 g bis(dimethylamino)methyl tertiary-butyl ether in 125 ml dimethylformamide (DMF) was heated at 140° C. under nitrogen for 18 hours. The solvent was removed in vacuo and the crystalline residue dissolved in boiling cyclohexane (about 3 L). The solution was filtered through filter paper containing charcoal and concentrated in vacuo to give 60 g (80%) 4-(2-dimethylamino-1-ethenyl)pyridine as light orange crystals.
