Reaction Steps

4-Fluoro-3-nitro-1H-pyrrolo[2,3-b]pyridine (0.300 g, 1.66 mmol) and 1-benzylpiperazine (0.350 g, 1.99 mmol) were placed in NMP (3 mL) and heated to 80° C. in a microwave for 30 minutes. The reaction was then poured into water and extracted with MTBE. The organic fractions were dried, filtered, and concentrated. The crude residue was slurried in minimal DCM, and then triturated with hexane to give 4-(4-benzylpiperazin-1-yl)-3-nitro-1H-pyrrolo[2,3-b]pyridine (0.425 g, 76.1% yield).
