The reactions of carbon suboxide with aromatic amines were found to give various 4-hydroxycarbostyril derivatives. The reaction between aniline and carbon suboxide usually gives malonanilide. However, it was found that the reaction of aniline with carbon suboxide in ether in the presence of aluminum chloride produced phenylcarbamoylacetic acid in a good yield and that cyclization to 4-hydroxycarbostyril occurred when the solvent was replaced by benzene before the decomposition of the reaction mixture with water. The solvent effect on the formation of 4-hydroxycarbostyrils and the possible reaction mechanism were discussed. |
