反応手順

5-Bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-amine (0.044 g, 0.19 mmol), nicotinic acid (0.0283 g, 0.230 mmol), and BOP-Cl (0.0584 g, 0.230 mmol) were placed in DMF (3 mL) at room temperature. Triethylamine (0.133 mL, 0.956 mmol) was then added, and the reaction was stirred for 1 hour at room temperature. The reaction was then diluted with 3M LiOH (aq., 0.5 mL) and stirred for 10 minutes. The reaction was then poured into saturated Na2CO3, extracted into DCM, and the organic fractions were combined, dried, filtered and concentrated to give a crude residue. The crude residue was triturated with 1:2 MeOH/DCM to give N-(5-bromo-4-fluoro-1H-pyrrolo[2,3-b]pyridin-3-yl)nicotinamide (0.035 g, 54.6% yield) as a solid.
