| titleOfInvention | Process for producing low-melting type 2-anilino-3-methyl-6- (N-ethyl-N-isopentylamino) fluorane |
| abstract | (57) [Summary] (Modified) SOLUTION: 2- (4 ′-(N-ethyl-N-isopentylamino) -2′-pydoxybenzoyl) benzoic acid and 4-methoxy-2-methyldiphenylamine Phthalide obtained by reacting with and in concentrated sulfuric acid is subjected to a ring closure reaction in a mixed solution of an organic solvent and an alkali hydroxide aqueous solution, and then an organic solvent layer containing fluorane obtained by this ring closure reaction is separated from an aqueous layer. After that, if necessary, this organic solvent layer is heated to completely dissolve fluorane in the organic solvent, and then the organic solvent layer is cooled to precipitate crystals, which is a low melting point type 2. -Process for producing anilino-3-methyl-6- (N-ethyl-N-isopentylamino) fluorane. [Effect] It is possible to provide a target substance which is reproducibly and substantially consists of α-form. |
