Reaction Steps

To a solution of 5-methoxyindole (1 g, 6.8 mmol) in 8 mL of DMF were added potassium hydroxide (0.92 g, 2.4 eq.) and methyl iodide (1 mL, 16 mmol). The resulting mixture was stirred at room temperature overnight. After removing volatile, the residue was diluted with EtOAc and washed with water (4×). The organic layer was dried and concentrated to afford 0.9 g (82%) 5-methoxy-1-methylindole. MS (EI): (M++1) 162.
