Reaction Steps

6-Nitroindole (1.0 g, 6.2 mmol) was successively added with acetic acid (2.5 mL), water (5.0 mL), and hexamethylenetetramine (1.2 g, 8.4 mmol), and then the mixture was stirred overnight at 120° C. in a sealed tube. The reaction mixture was added with water, and the precipitated solid was collected by filtration, and then dried to obtain 6-nitro-1H-indole-3-carboxaldehyde (0.91 g, 77%).
