Procedure
N,N,N′,N′-Tetramethyldiaminomethane (2.2 mL, 15.6 mol) in acetic acid (30 mL) was added dropwise over 60 min to a solution of 4-nitroindole (2.30 g, 14.2 mol) in acetic acid (30 mL). After 3.5 h, the reaction was cooled to 0° C., and 20% aqueous sodium hydroxide was added to adjust the pH to 11. The mixture was extracted with CHCl3 (3×300 mL) and the combined organic extracts were dried over Na2SO4, filtered, and concentrated in vacuo to give the title compound. MS: ml/=220 (M+1).
