The present invention relates to novel intermediates useful for the preparation of novel phenylaminopyrimidine derivatives, novel phenylaminopyrimidine derivatives. Pharmaceutical composition containing the novel phenylaminopyrimidine derivatives and processes for their preparation. The invention particularly relates to novel Phenyl pyrimidine amine derivatives of the general formula (I). The novel compounds of the formula 1 can be used in the therapy of Chronic Myeloid Leukemia (CML). Since the IC
50
; 191 values of these molecules are in the range 0.1 to 10.0 nm, these novel compounds are potentially useful for the treatment of CML.
The present invention relates to a particular form of the (3,5-bis trifluoromethyl)-N-[4-methyl-3-(4-pyridin-3yl-pyrimidin-2ylamino)-phenyl]-benzamide (formula I), processes for the preparation thereof, pharmaceutical compositions containing this crystal form, and their use as anti tumor agent in humans. The compound of formula I, also known as AN-019, is:
This invention relates to a process for the preparation of (3-trifluoromethylsulfonyl)-N-[4-methyl-3-(4-pyridin-3yl-pyrimidin-2ylamino)-phenyl]-benzamide (formula (I)) starting from 4-methyl-2-nitro-aniline (formula (II)) through intermediates (3-trifluoromethylsulfonyl)-N-[4-methyl-3-nitrophenyl]-benzamide (formula (III)), (3-trifluoromethylsulfonyl)-N-[3-amino-4-methylphenyl]-benzamide (formula (IV)) and (3-trifluoromethylsulfonyl)-N-[
