| titleOfInvention | The method for preparing high-purity tolvaptan intermediate |
| abstract | The invention provides a method for preparing a high-purity tolvaptan intermediate. Specifically, the present invention provides a tolvaptan intermediate N-[4-[(7-chloro-2,3,4,5-tetrahydro-5-oxo-1H-1-benzoazepine Hetero-1-yl) carbonyl]-3-methylphenyl]-2-methylbenzamide (formula II) purification method. The crude product containing the compound of formula II is recrystallized in an organic solvent composed of ester, halogenated alkanes and ether, and the purity of the obtained compound of formula II is preferably greater than 99.00%. |
