Reaction Steps

TEA (0.82 mL, 5.91 mmol) was added to a mixture of 4,5-difluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (0.20 g, 1.18 mmol; Example 13, Step C), (R)-2-methoxypropanoic acid (0.25 g, 2.37 mmol) and BOP-Cl (0.60 g, 2.37 mmol) in DCM (5 mL) at room temperature. The reaction was stirred at room temperature for 1 hour, and then a 2N LiOH solution (3 mL) was added. The mixture was stirred at room temperature for 30 minutes, and water (10 mL) and ethyl acetate (30 mL) were added. The organic layer was separated, washed with brine, dried (sodium sulfate) and concentrated in vacuo. The residue obtained was purified by chromatography on silica gel (hexane:ethyl acetate 1:2) to give (R)-N-(4,5-difluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-2-methoxypropanamide (0.21 g, 70%) as a solid.
