Reaction Steps

98.6 parts of 75 percent pure sodium salt of α-formyl-β-formylaminopropionitrile and 81.5 parts of dimethylammonium chloride in 700 parts by volume of chloroform are refluxed for 1.5 hours, during which time 8.5 parts (theory: 9 parts) of water are eliminated. The mixture is filtered, the filtrate is concentrated to dryness and the product is recrystallized from methanol. 43.0 parts of α-dimethylaminomethylene-β-formylaminopropionitrile of melting point 90° C. are obtained.
