Use of an aniline depleted in electron to release hydrochloric acid present in a reaction mixture and method for displacing, at least partially, an aniline from its chlorhydrate |
摘要 |
The invention concerns a method for displacing, at least partially, an aniline from its chlorhydrate, characterized in that said aniline is selected among anilines whereof the conjugate acid has a pKa not more than 6 and in that it consists in a step wherein it is subjected at a temperature not less than 50° C., advantageously about 70° C. to a reaction medium containing said chlorhydrate at least partially dissolved in a weakly polar solvent. The invention is applicable to organic synthesis.
