Reaction Steps

To a solution of methyl 4-(2-fluoro-4-nitrophenoxy)-1H-pyrrolo[2,3-b]pyridine-3-carboxylate (230 mg, 0.69 mmol) in a mixed solvent (10 mL of MeOH and 10 mL of THF) were added ammonium chloride (185 mg, 3.45 mmol) and zinc dust (226 mg, 3.45 mmol). The reaction mixture was stirred at room temperature overnight, diluted with EtOAc (50 ml), and filtered through a pad of Celite®. The filtrate was concentrated in vacuo to give the desired product (207 mg, 100%) as a yellow solid. MS(ESI+) m/z 302.2 (M+H)+.
