Reaction Steps

A 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 was treated with tetra-n-butyl ammonium cyanide in acetonitrile at 100° C. for 4 hours. Solvent was concentrated to dryness and purified by chromatography to give a protected intermediate that was de-protected similar to step 5, Example 76, to give 4-((S)-1-methanesulfonyl-piperidin-3-ylamino)-5-(5H-pyrrolo[2,3-b]pyrazin-2-yl)-pyrimidine-2-carbonitrile.
