PROCESSES FOR THE PREPARATION OF FESOTERODINE
-
, (2012/03/26)
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.

Page/Page column 12, (2008/06/13)
The present disclosure relates to a process for the preparation of 2-(3-diisopropylamino-1-phenylpropyl)-4-(hydroxymethyl)phenol or its phenolic monoesters or salts thereof, characterized by the steps of a) reacting a compound of formula (II) with a mixture of MeMgCl and Mg in a solvent, b) optionally reducing the temperature of the Grignard reagent to a lower temperature than in step a), and reacting the resulting Grignard reagent with an excess of a carbonate in a solvent, to obtain a compound of formula (III) wherein A is a C1-C6 alkyl group, and then further reacting the compound of formula (III) in a known manner to obtain the desired end product.
