Procedure
This was an adaptation of the procedure reported by R. G. Lacoste and A. E. Martel in Inorganic Chemistry 1964, 3(6), 881, for the preparation of N-[2-(4-pyridyl-ethyl]ethylene diamine. To a 250 ml three neck round bottom flask, fitted with a dropping funnel, a reflux condenser, and magnetic stirring, was added 12.02 g (0.2 mol) ethylene diamine, 24 g distilled water, and 31.50 g (0.3 mol) freshly distilled 4-vinylpyridine. The temperature was maintained at 20°-30° C. while 12.0 g glacial acetic was added through the dropping funnel. After all the acetic acid was added, the reaction mixture was heated on the steam bath for two hours. The product was fractionally distilled to give 11.48 g (35% yield). The product was characterized by IR and NMR.
