Abstract
The salts of alkyl dicyanoacetates and methyl 3-amino-3-chloro-2-cyanoacrylate react in chloroform with N-(dichloromethylene)dimethylammonium chloride to give 4-chloro-5-cyano-2-dimethyl- amino-6H,3-oxazin-6-one. The chloro atom of this compound can be easily substituted by alcohols or amines in good yield.Keywords
