In a dioxane solution of ((S)-1-methanesulfonyl-piperidin-3-yl)-{2-methanesulfonyl-5-[5-(2-trimethylsilanyl-ethoxymethyl)-5H-pyrrolo[2,3-b]pyrazin-2-yl]-pyrimidin-4-yl}-amine derived from Example 84, step 1, N-methylpiperazine was used to displace the methylsulfone similar to examples above and the de-protection step was similar to step 5, Example 76, to give ((S)-1-methanesulfonyl-piperidin-3-yl)-[2-(4-methyl-piperazin-1-yl)-5-(5H-pyrrolo[2,3-b]pyrazin-2-yl)-pyrimidin-4-yl]-amine.
