General description

Ethyl (4-fluorobenzoyl)acetate on condensation with benzofurazan oxide yields 2-(carboethoxy)-3-(4′-fluoro)phenylquinoxaline1,4-dioxide.

Application

Reactant used as a precursor in:

• Condensation reactions with diamines via C-C bond cleavage for synthesis of benzimidazoles and perimidines for possible use as antimalarial treatments
