Electric Literature of 40876-98-0,Some common heterocyclic compound, 40876-98-0, name is Sodium 1,4-diethoxy-1,4-dioxobut-2-en-2-olate, molecular formula is C8H11NaO5, traditional synthetic route has been very mature, but the traditional synthetic route has various shortcomings, such as complicated route, low yield, poor purity, etc, below Introduce a new synthetic route.
General procedure: A mixture of0.01 mol of diethyl oxalylacetate sodium salt, 0.01 molof aromatic aldehyde, and 0.01 mol of urea was heatedat reflux in 10 mL of acetic acid for 2 h. The mixturewas kept for 24 h at room temperature, the precipitatewas filtered off and recrystallized from ethanol.
These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route Sodium 1,4-diethoxy-1,4-dioxobut-2-en-2-olate, its application will become more common.
