摘要:
The present invention is concerned with a process of preparing (R)-lacosamide. The process comprises providing an (R,S)-lacosamide precursor and contacting the same with at least an enzyme in the presence of a solvent. The enzyme either stereoselectively hydrolyzes or acetylates an (R)- or (S)-enantiomer of the (R,S)-lacosamide precursor. The process further comprises where appropriate also concurrently, or successively, employing one or more reagents capable of converting the hydrolysed or acetylated (R)- or (S)-enantiomer to (R)- lacosamide.
摘要:
The invention relates to the malic acid salt of N-[2-(diethylamino)ethyl]-5- formyl-2,4-dimethyl-lH-pyrrole-3-carboxamide, to the use thereof as an intermediate for preparing the malic acid salt of sunitinib, and to pharmaceutical compositions comprising said malic acid salt of sunitinib.
摘要:
This invention provides improved processes for the preparation of 5-chloro-2-methyl-2,3,3a,12b-tetrahydro-1 H- dibenzo[2,3:6,7]oxepino[4,5-c]pyrrole, asenapine. These processes allow the preparation of asenapine at industrial scale in good yields and high stereoselectivity.
摘要:
The invention relates to 2-amino-3-benzoylbenzeneacetamide, i.e. nepafenac, crystals having reduced chargeability, to processes for the preparation thereof, and to the use thereof for preparing pharmaceutical formulations.
