Reaction Steps

To a mixed slurry of (1S,2S)-2-[[2-(5-chloro-1H-pyrrolo[5,4-b]pyridin-3-yl)-5-fluoro-pyrimidin-4-yl]amino]cyclohexane-1-carboxylic acid, 553, (0.090 g, 0.231 mmol), in ethanol (1.5 mL) at room temperature was added HCl (0.577 mL of 4 M solution, 2.309 mmol). The solution was warmed to 50° C. After 6 hours, the mixture was basified with 1N NaOH, brine was added and the aqueous layer was and extracted repeatedly with EtOAc. The organic layer was dried over MgSO4, and filtered through a short plug of silica gel and concentrated in vacuo to provide the desired product.
