To a stirred solution of methyl (1S,2S)-2-(2-(5-chloro-1-tosyl-1H-pyrrolo[2,3-b]pyridin-3-yl)-5-fluoropyrimidin-4-ylamino)cyclohexylcarbamate, 23c, (0.09 g, 0.16 mmol) in THF (3 mL) at room temperature was added LiAlH4 (0.06 g, 1.66 mmol) and the mixture was stirred at room temperature for additional 2 hours. The reaction was quenched with 0.06 mL KOH (5% aq) followed by water (3×0.06 mL). Then, additional Et2O (6 mL) was added and stirring was continued for 20 minutes. The milky white suspension was filtered and rinsed with EtOAc and the cake was rinsed with additional EtOAc. The combined organic phases were concentrated in vacuo and purified by preparative HPLC followed by preparative TLC to provide the desired product as the free base that was then converted to the HCl salt by treatment with HCl (4N in dioxane).
