Participants

Reaction Steps

A solution of 2-chloro-3-phenyl-5,8-dimethoxyquinoline (200 mg, 0.67 mmol) was refluxed for 3 hours in acetic acid (1.5 ml) and water (0.05 ml.) After the solvent was evaporated, the residue was dissolved in water, basified with aqueous ammonium hydroxide 25% and extracted with chloroform (3×25 ml). The combined chloroform layers were dried over sodium sulfate and evaporated, yielding an essentially pure residue of 187 mg (100%) of 3-phenyl-5,8-dimethoxy-2-(1H)-quinolinone. m.p. 207 (CDCl3).
