The invention relates to improved process for the preparation of fesoterodine and its pharmaceutically acceptable salt, specifically fesoterodine fumarate of formula (1). The invention relates to solid state forms of a novel salt of fesoterodine and process for the preparation thereof. The invention also relates to highly pure fesoterodine fumarate substantially free of impurity X at RRT 1.37. The invention also provides solid particles of pure fesoterodine fumarate wherein 90 volume-percent of the particles (D90) have a size of higher than 200 microns.
