    摘要: A process is described for preparing fesoterodine and/or fesoterodine fumarate comprising the esterification of (R)-feso deacyl with isobutyric acid or a precursor thereof, such as an isobutyryl halide or the isobutyric acid anhydride to give fesoterodine, in a mixture of water at alkaline pH and/or at least one organic solvent. This process allows obtaining products with high yields and purities, and in particular a product having a content of (R)-2-[3-(diisopropylamino)-1-phenylpropyl]-4-isobutyroyloxymethyl-phenyl isobutyrate less than 1% by mole and a content of (R)-2-[3-(diisopropylamino)-1-phenylpropyl]-4-(hydroxymethyl)phenol less than 0.05% by mole.

    摘要: Described is a new process for producing temozolomide, comprising the reaction between 5-aminoimidazole-4-carboxamide and N-succinimidyl-N′-methyl carbamate and the subsequent reaction of the thus obtained carbamoyl 5-aminoimidazole-4-carboxamide with sodium nitrite. Temozolomide is then purified by chromatography on adsorbent polymeric resin and subsequent crystallization from water and acetone.

    摘要: 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.
