An improved process for the preparation of propiomazine maleate |
| abstract |
The present invention relates to an improved process for the preparation of highly pure Propiomazine Maleate of formula-I. More particularly, the invention relates to a cost-effective process, which provides Propiomazine maleate of formula-I with high purity, which is free from isomeric impurity of formula-III, specifically isopropiomazine. The isomeric impurity is controlled during the preparation of Propiomazine maleate. (I) |
