To a solution of 5-butyl-1H-indole-2-carbaldehyde (75 mg, 0.37 mmol) and methyl iodide (57 mg, 0.40 mmol) in 0.75 mL dimethylformamide was added potassium carbonate (57 mg, 0.41 mmol). The resulting suspension was stirred vigorously at 150° C. in a sealed vial under argon for 1 h. Solids were filtered and the liquor concentrated before being subjected to chromatography on silica gel (40% ethyl acetate in hexanes) to give 5-butyl-1-methyl-1H-indole-2-carbaldehyde (15 mg, 18%).
