A mixture of 2-chloro-N-(1H-indazol-6-yl)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-4-amine (340 mg, 0.78 mmol), 1-(4-(4-aminophenyl)piperazin-1-yl)ethanone (204 mg, 0.93 mmol) and trimethylsilyl chloride (TMSCl) (0.200 mL, 1.58 mmol) in n-butyl alcohol (8 mL) was heated at 116° C. overnight. More 1-(4-(4-aminophenyl)piperazin-1-yl)ethanone (204 mg, 0.93 mmol) was added. The mixture was then stirred at 116° C. for another 48 h. It was then purified by HPLC to give 1-(4-(4-(4-(1H-indazol-6-ylamino)-7-tosyl-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)phenyl)piperazin-1-yl)ethanone as a solid (126 mg).
