Heterocyclic amines were acetoacetylated with 2,2,6-trimethyl-1,3-dioxen-4-one and the obtained compounds reacted on the reactive methylene group to give C-substituted products. Nitrosation, followed by reduction afforded a pyrazine derivative. Azido- or chloroacetamide were also acetoacetylated, with heterocyclic amines, the corresponding enamines were prepared and reduction of the azido group of
