反応手順
A mixture of 4-(2-cyanoethyl)pyridine (1.32 g, 0.01M) and N-ethyl-1,2-diaminoethane mono-p-toluenesulfonate (5.5 g, 0.02M) were heated at 190° C. for 4 hrs under nitrogen. The reaction mixture was dissolved in ethanol (30 ml) and sodium ethoxide (0.02M) in ethanol (50 ml) was added. The mixture was filtered and the filtrate was stripped to dryness and distilled at 130° C./0.2 mmHg to yield 4-[2-(1-ethyl-4,5-dihydro-imidazol-2-yl)ethyl]-pyridine (1.2 g, 60% yield).
