- Mix 42.5g (60 ml, 0.58 mol) of freshly distilled diethylamine and 26.5g (33 ml, 0.5 mol) of pure acrylonitrile in a 250-ml round-bottomed flask fitted with a reflux condenser.
- Heat at 50 °C in a water bath for 10 hours and then allow to stand at room temperature for 2 days.
- Distil off the excess of diethylamine on a water bath, and distil the residue under reduced pressure.
- Collect the 3-(diethylamino)propionitrile at 75-77 °C/11 mmHg; the yield is 54g (86%).
