Reaction Steps

To a solution of 6-nitro-2-phenyl-1H-indole (106 mg, 0.44 mmol) and 18-Crown-6 (130 mg, 0.49 mmol) in anhydrous tetrahydrofuran (2 mL) at room temperature was added potassium tert-butoxide (55 mg, 0.49 mmol) followed by methyl iodide (31 μL, 0.49 mmol). The solution was stirred at room temperature for 30 min. Tetrahydrofuran was removed in vacuo. Ethyl acetate was added, and the organic layer was washed with water and then brine. The combined organic layers were dried over anhydrous MgSO4 and evaporated to afford 110 mg (98%) of the title compound.
