Abstract

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 (II). The invention also relates to the novel polymorphs of the pharmaceutically acceptable salts of darifenacin and the methods for their preparation.
