Independent claims are included for: (1) the preparation of (I); (2) the preparation of a 2-chloro-pyrimidine compound of formula (IV) comprising reaction of 2,4-dichloro-pyrimidine compound of formula (VI) with a nucleophilic compound of formula (H-X-R 2>); (3) compound of formula (IV); (4) the preparation of a nucleophilic compound of formula (VII) comprising imination of a thioether compound of formula (IX) to give a sulfimide compound of formula (VIII) and reduction of the nitro-group of (VIII); and (5)ccompound of formula (VII). [Image] [Image] ACTIVITY : Cytostatic; Cardiovascular-Gen; Vasotropic; Antiarteriosclerotic; Antiinflammatory; Gastrointestinal-Gen; Gynecological. MECHANISM OF ACTION : Protein kinase inhibitor. The ability of (I) to inhibit protein kinase was tested using cyclin-dependent kinase-2 assay. The results showed that (RS)-S-{4-[(5-bromo-4-{[(R)-2-hydroxy-1,2-dimethylpropyl]amino}pyrimidin-2-yl)amino]phenyl}-N-mesyl-S-methylsulfimide exhibited an IC 5 0 value of 6 nM.
