5-Nitroindole-3-carboxaldehyde (2 g) was dissolved in N,N-dimethylformamide (40 ml), and potassium carbonate (4.0 g) and methyl iodide (5 ml) were added thereto, followed by stirring at 60° C. for 24 hours. The reaction solution was subjected to partitioning with chloroform, methanol and water, and the organic layer was dried over magnesium sulfate. After concentration under reduced pressure, the residue was rinsed with ethyl acetate to give 1-methyl-5-nitroindole-3-carboxaldehyde (Compound III-2, 1.99 g).
