PROCESS FOR PRODUCING PURIFIED PIPERIDINE DERIVATIVE |
摘要 |
A process for producing a purified piperidine derivative, pyridine derivative, or quinoline derivative useful as an intermediate or starting material for medicines and agricultural chemicals through short steps and easy operations without necessitating a special reagent or apparatus. Any of those derivatives, which is insoluble or sparingly soluble in water, is dissolved in a medium under acidic conditions to form a salt, and the resultant solution is made basic to thereby precipitate the target compound.
