실험 절차

To a solution of 2-[5-chloro-1-(p-tolylsulfonyl)pyrrolo[5,4-b]pyridin-3-yl]-5-fluoro-N-[(3S)-3-piperidyl]pyrimidin-4-amine, 1c, (0.16 g, 0.32 mmol) in 1,2-dichloroethane (2 mL) was added 1H-imidazole-2-carbaldehyde (0.03 g, 0.36 mmol) followed by 2 drops of acetic acid and Na(OAc)3BH (0.10 g, 0.49 mmol). The reaction mixture was heated at 60° C. for 18 h. The mixture was cooled to room temperature and diluted with aqueous saturated NaHCO3 solution. The aqueous phase was extracted twice with EtOAc. The combined organic phases were dried (MgSO4), filtered and concentrated in vacuo. The crude residue was purified via silica gel chromatography (0-20% MeOH/CH2Cl2) to afford the product, 4a.
