Procedure
5-chloro-3-(5-fluoro-4-methylsulfinyl-pyrimidin-2-yl)-1-(p-tolylsulfonyl)-pyrrolo[2,3-b]pyridine, 19b, (2.04 g, 4.39 mmol) and methyl N-[(1R,3S)-3-aminocyclohexyl]carbamate (0.60 g, 3.14 mmol) were suspended in THF (16 mL) and heated in the microwave to 130° C. for 20 minutes. Lithium hydroxide (15.67 mL of 1M solution, 15.67 mmol) was added, and the resulting mixture was heated in the microwave for 20 min at 130° C. The resulting solution was diluted with water (150 mL) and ethyl acetate (200 mL) and the layers were separated. The aqueous layer was extracted with EtOAc (100 mL) and t organic layers were combined, dried over Na2SO4 and concentrated in vacuo. The crude product was purified by silica gel chromatography (40-100% EtOAc/hexanes) followed by treatment of the pure fractions with 4N HCl in dioxane to provide the hydrochloride of compound, 570, as an off white solid.
