Procedure

4-Methanesulfonyl-3-nitro-benzoic acid (72 mg, 0.29 mmole) was dissolved in DMA (3 ml) and thionyl chloride (0.29 mmole) was added at ambient temperature. After the mixture was stirred for 5 minutes N2-(4-Amino-phenyl)-5-bromo-N4-[2-(3H-imidazol-4-yl)-ethyl]-pyrimidine-2,4-diamine (100 mg, 0.26 mmole, prepared according to procedure 21) was added and the reaction was allowed to stir overnight. After extraction with bicarbonate solution and ethyl acetate (3×) the combined organic layers were dried over magnesium sulfate and the solvent was removed under reduced pressure. The crude product was purified by flashmaster chromatography on silica gel to provide 37 mg of N-(4-{5-Bromo-4-[2-(3H-imidazol-4-yl)-ethylamino]-pyrimidin-2-ylamino}-phenyl}-4-methanesulfonyl-3-nitro-benzamide (23% yield). ESI-MS: 602.
