| titleOfInvention | A kind of preparation method of blonanserin process impurity F |
| abstract | The present invention relates to a preparation method of impurity F in blonanserin process. Reaction with the chlorinating reagent phenylphosphoryl dichloride to obtain 2-chloro-4-(2-fluorophenyl)-5,6,7,8,9,10-hexahydrocyclooctanopyridine (formula II), The formula II is then reacted with N-ethylpiperazine under the catalysis of potassium iodide to obtain the blonanserin process impurity F (formula (I)). The process is simple, the operation is convenient, the chromatographic purity is over 99.0%, and the yield is high. |
