Acrylonitrile → N-[2-(chroman-3-yl)ethyl]-N-(2-cyanoethyl)-amine

Participants

Reaction Steps

17.7 g (0.1 mol) of 3-(2-aminoethyl)chroman are dissolved in 100 ml of methanol, and then 10.5 g (0.1 mol) of triethylamine and 5.84 g (0.11 mol) of acrylonitrile are added to the solution. The reaction mixture is stirred for 15 hours at room temperature and then concentrated under a water-jet vacuum. The residue is taken up in diethyl ether and washed neutral with ice-water. The ethereal phase is dried over potassium carbonate and concentrated by evaporation. N-[2-(chroman-3-yl)ethyl]-N-(2-cyanoethyl)-amine is thus obtained in the form of a pale yellow oil.
