  • Processes of preparing highly pure telmisartan form A, suitable for pharmaceutical compositions
    Publication number: 20060276525
    Abstract: Processes are disclosed for preparing Telmisartan form A, which is free-flowing and which does not contain electrostatic charge and is thus industrially process-able. The free-flowing Telmisartan form A is prepared by crystallization from a polar organic solvent e.g., DMSO, DMF, DMA, NMP, or water and is suitable for use in pharmaceutical compositions. A process is also disclosed for preparing highly-pure Telmisartan form A by precipitation from aqueous solutions.

  • Process for the reduction of (S)-2-amino-6-propionamido-4,5,6,7-tetrahydrobenzo-thiazole
    Publication number: 20060069263
    Abstract: A process is disclosed for the reduction of (S)-2-amino-6-propionamido-4,5,6,7-tetrahydrobenzothiazole, which comprises reacting (S)-2-amino-6-propionamido-4,5,6,7-tetrahydrobenzothiazole with a borane reagent in the presence of suitable organic solvent to yield (S)-2-amino-6-propylamino-4,5,6,7-tetrahydrobenzothiazole base, which may be converted to an acid addition salt thereof. The process provided herein can be easily, conveniently and inexpensively scaled-up.
