Reaction Steps

To a solution of tert-butyl (3S)-3-[[2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[5,4-b]pyridin-3-yl]-5-fluoro-pyrimidin-4-yl]amino]piperidine-1-carboxylate, 1b, (0.93 g, 1.55 mmol) in methanol (10 mL) was added sodium methoxide (10 mL of 1M solution). The reaction mixture was warmed to 45° C. After stirring for 30 minutes the reaction was to cooled to room temperature and quenched by addition into water. The mixture was diluted with EtOAc and the layers were separated. The organic phase was washed with brine, dried (MgSO4), filtered and concentrated in vacuo. The resulting residue was purified by silica gel chromatography (0-100% EtOAc/Hexanes) to afford the desired product, 2b.
