| titleOfInvention | Production of fluoran compound |
| abstract | PURPOSE: To obtain the title compound useful as an electron donating colorless dye by treating a fluoran compound having cyclic ether bond on a substituent group with a hydrogen halide. n CONSTITUTION: A fluoran compound e.g. a compound expressed by the formula [R 1 and R 4 are (substituted) alkyl or aryl or H; R 2 is group having cyclic ether bond; R 3 is alkyl, halogen or H; Y and Z are H or alkyl; ring A is 5-6-membered aromatic ring which may contain hetero atom] having a cyclic ether bond on a substituent group is treated with a hydrogen halide (preferably hydrogen chloride, hydrochloric acid or hydrobromic acid) to provide the aimed compound (e.g. 2-anilino-3-methyl-6-N-ethyl-N5-chloro-2-hydroxyamylaminofluoran). n COPYRIGHT: (C)1991,JPO&Japio |
