The original synthesis of cinnamic acid involves the Perkin reaction, which entails the base-catalysed condensation of acetic anhydride and benzaldehyde. Rainer Ludwig Claisen (1851–1930) described the synthesis of cinnamate esters by the reaction of benzaldehyde and esters. The reaction is known as the Aldol condensation (with accompanying hydrolysis of the anhydride).
Sodium ethoxide (also is the organic compound with the formula C2H5ONa) is a white to yellowish powder that dissolves in polar solvents such as ethanol. It is commonly used as a strong base. Few procedures have been reported to the anhydrous solid. Instead the material is typically prepared in a solution with ethanol. It is commercially available and as a solution in ethanol. It is easily prepared in the laboratory by treating sodium metal with absolute ethanol.
