| abstract |
An object of the present invention is to provide a production method for obtaining a quinophthalone compound in a high yield. The compound represented by the general formula (1) in a hydrocarbon solvent: Embedded image [Wherein R 1 and R 2 are each independently a hydrogen atom, an optionally substituted alkyl group, —CONR 3 R 4, or —COOR 5 (R 3 to R 5 are each independently a hydrogen atom, an optionally substituted alkyl group or Represents an aryl group which may be substituted). A quinophthalone compound represented by the formula (2): Embedded image Wherein R 1 and R 2 are the same as those in the above general formula (1), and R 6 and R 7 each independently represent a hydrogen atom or an optionally substituted alkyl group. .
