Putrescine → 3-((4-Aminobutyl)amino)propanenitrile

Participants

Reaction Steps

To a solution of 1,4-diaminobutane (8.6 g, 97.6 mmol) in methanol (3.0 ml) was added a solution of acrylonitrile (6.2 g, 116.8 mmol) in methanol (3.0 ml) at 0° C., and the mixture was stirred for 12 hours. Evaporation of the solvent in vacuo afforded N-(2′-cyanoethyl)-1,4-diaminobutane as a colorless oil (11.0 g, 80%). 1H NMR (400 MHz, CDCl3) δ: 1.45 (4H, br, —CH2CH2—), 2.46 (2H, t), 2.58 (2H, t), 2.62 (2H, t) and 2.84 (2H, t).
