To 27.0 g. of 2-pyrimidinecarboxaldehyde and 11.3 g. of dimethylamine (neutralized with hydrochloric acid) is added, with stirring and cooling, 17.9 g. of potassium cyanide in a small amount of water. The mixture is allowed to stand overnight and ether is added. Concentrating and distilling the residue gives 2-dimethylamino-2-(2-pyrimidyl)acetonitrile.
