| titleOfInvention | Preparation process of 1-chlorocarbonyl-4-piperidinopiperidine pr hydrochloride thereof |
| abstract | The present invention provides a highly safe and easily operable process for preparing 1-chlorocarbony1-4-piperidinopiperidine or hydrochloride thereof in a high yield.Described specifically, the present invention relates to a process for preparing 1-clorocarbony1-4-piperidinopiperidine or hydrochloride thereof, which comprises reacting 4-piperidinopiperidine with a trialkylsily1 halide to obtain a 4-piperidinopiperidiny1 trialkylsily1, reacting it with a carbon dioxide gas to obtain a 4-piperidinopiperidiny1 trialkylsily1 carbamate derivative, reacting the derivative with thiony1 chloride or the like to obtain 1-chlorocarbonyl-4-piperidinopiperidine hydrochloride and optionally treating it with a strong base. |
