Versuchsvorschrift

A mixture of 7-nitro-1H-indole (3 g, 18.5 mmol), 40% aqueous dimethylamine (3.12 mL, 27.7 mmol) and 37% aqueous formaldehyde (1.57 mL, 19.3 mmol) was stirred for three days at ambient temperature. The reaction mixture was diluted with H2O (20 mL) followed 15% aqueous NaOH (200 mL) and extracted with CHCl3 (3×200 mL). The combined organic extracts were dried over Na2SO4, filtered, and concentrated in vacuo to give the title compound in sufficient purity for use in the next step. MS: m/z=181 (M+1).
