反応手順
TEA (0.61 mL, 4.35 mmol) was added to 5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (0.20 g, 0.87 mmol, Example 1, Step H), 1-methyl-6-oxo-1,6-dihydropyridine-3-carboxylic acid (0.17 g, 1.13 mmol) and BOP-Cl (0.33 g, 1.30 mmol) in DCM (10 mL). The reaction was stirred at room temperature for 1 hour, and then a LiOH solution (3 mL, 2N) was added. The mixture was stirred for 30 minutes, and water (10 mL) was added. The solid formed was collected by filtration, washed with DCM (10 mL) and dried to give N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)-1-methyl-6-oxo-1,6-dihydropyridine-3-carboxamide (0.22 g, 69% yield) as a solid.
