A New Synthesis of Bipyrimidones by Reaction of Hydrazine Derivatives with Ethyl Carbonochloridate

Hydrazine derivatives react with ethyl carbonochloridate through a double condensation process.The new compounds obtained afford 2,2'-dioxo-1,1'2,2'-tetrahydro-1,1'-bipyrimidines when treated with an alkyllithium reagent.
