Process for the perparation of sunitinib and its acid addition salts thereof |
| abstract |
The present invention relates to an improved process for the preparation of Sunitinb. The process involves the activation of 5-((Z)-(5-fluoro-2-oxoindolin-3-ylidene) methyl)-2,4-dimethyl-1H-pyrrole-3carboxylic acid to corresponding suitable carboxylic acid activating group. The present invention also relates to novel acid addition salts of Sunitinb and preparation thereof. |
