반응 단계

Acrylonitrile (10.1 ml, 1.1 eq) is added slowly to a solution cooled down to approximately 4° C. of 2-[2-(methylamino)ethyl]pyridine (19.5 ml, 1 eq) in methanol (200 ml). The reaction medium is then stirred for 3 hours at approximately 20° C. then concentrated under reduced pressure at 40° C. in order to produce 3-[(2-pyridin-2-ylethyl)amino]propanenitrile in the form of a yellow oil (25.6 g, 96% yield).
