| titleOfInvention | Method for producing fluoran compounds |
| abstract | (57) [Problem] To provide an industrially advantageous production method of a fluoran compound. The benzophenone carboxylic acid derivative represented by the general formula (1) is reacted with a phenol derivative represented by the general formula (2) in a condensing agent. For producing fluoran compounds. [Wherein, R 1 and R 2 represent an alkyl group, a cycloalkyl group, It means an alkoxyalkyl group, a tetrahydrofurfuryl group, or a phenyl group which may have a substituent. Also, R 1 And R 2 may be linked to form a ring. M represents a sodium atom or a potassium atom. ] [Wherein, R 3 represents a hydrogen atom or an alkyl group, X 1 represents a hydrogen atom or an alkyl group, X 2 represents a hydrogen atom, an alkyl group, a halogen atom, or an amino group, and X 3 represents a hydrogen atom. Means X 1 or X 2 adjacent to X 3 Can be linked to form a benzene ring. ] [Wherein, R 1 , R 2 , X 1 , X 2 , and X 3 have the same meaning as described above. ] |
