Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: Compound 7b was prepared following procedures similar to those described previously in Example 1, step A, substituting 7a for i-2d and 2,4,6-triisopropylbenzenesulfonyl chloride for i-5f, respectively. m/z (ES) 503 (MH+Na)+

Conditions: temp:50.01; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 5-fluoro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine, 44c, (5.9 g, 10.5 mmol) and tert-butyl N-[(1R,3S)-3-aminocyclohexyl]carbamate (3 g, 12.60 mmol) were dissolved in THF (100 mL). The reaction mixture was heated to 50° C. for 6 hours, then cooled to room temperature. Celite was added and the solvent was removed under reduced pressure. The Celite-supported residue was purified by silica gel chromatography (20-80% EtOAc/hexanes gradient to provide 3.7 g of tert-butyl N-[(1R,3S)-3-[[5-fluoro-2-[5-fluoro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]pyrimidin-4-yl]amino]cyclohexyl]carbamate. cooled to room temperature Celite was added the solvent was removed under reduced pressure The Celite-supported residue was purified by silica gel chromatography (20-80% EtOAc/hexanes gradient

Procedure: tert-Butyl N-[(1R,3S)-3-aminocyclohexyl]carbamate, 20a, (0.15 g, 0.70 mmol) and 5-chloro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridine, 1a, (0.49 g, 1.05 mmol) were dissolved in THF (30 mL) and allowed to stir at room temperature overnight. The solvent was evaporated under reduced pressure and the residue was purified by two rounds of silica gel chromatography—first with (0%-10% MeOH/CH2Cl2) second with (10%-50% EtOAc/hexanes) to provide tert-butyl N-[(1R,3S)-3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[2,3-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]cyclohexyl]carbamate (20b) (330 mg, 38%).
