Abstract
With the present method, a process which can be employed industrially can be used for the first time for the direct production of aminocyanoacetamide. The method is based on the reaction of cyanoacetamide with nitrites to form nitrosocyanoacetamide at a pH of around 2 and on the subsequent catalytic hydrogenation of nitrosocyanoacetamide to form aminocyanoacetamide.
