NOVEL AND IMPROVED PROCESSES FOR THE PREPARATION OF INTERMEDIATES OF DARIFENACIN, DARIFENACIN AND ITS PHARMACEUTICALLY ACCEPTABLE SALTS

The present invention relates to novel and improved processes for the preparation of intermediates of darifenacin, darifenacin and its pharmaceutically acceptable salts. Darifenacin is chemically known as 3 -(S)-(-)-(l -carbamoyl- 1,1 -diphenylmethyl)-l- [2- (2,3-dihydro benzofuran-5-yl)ethyl]pyrrolidine and represented by formula-2. The invention also relates to the novel polymorphs of the pharmaceutically acceptable salts of darifenacin and the methods for their re aration.
