Abstract: The present invention regards an improved and industrially advantageous process for the preparation of the 2-hydroxy-4-phenyl-3,4-dihydro-2H-chromen-6-yl-methanol intermediates, also called “feso chromenyl” and (R)-2-[3-(diisopropylamino)-1-phenylpropyl]-4-(hydroxymethyl)phenol, also called “(R)-feso deacyl”, which are in turn used in the synthesis of fesoterodine and in particular of fesoterodine fumarate. This process utilises reagents which are non-toxic and manageable at industrial level and enables obtaining a new stable and non-hygroscopic crystalline form of the key intermediate “(R)-feso deacyl”, called form B.
