Reaction Steps
The 2-phenylaminomethylene-malonic acid diethyl ester was refluxed in Dowtherm® for 15 min to 2 h. The reaction mixture was cooled to 80° C. and solid was collected by filtration and washed with hexane to yield crude ethyl 4-hydroxy-quinoline-3-carboxylate 2a which was used in next step without further purification.
