Dimethylamine → 6-Nitrogramine

Participants

Reaction Steps

A solution of dimethylamine (25 g, 0.17 mol) and formaldehyde (14.4 mL, 0.15 mol) in acetic acid (100 mL) was stirred at 0° C. for 30 min. To this solution was added 6-nitro-1H-indole (20 g, 0.12 mol). After stirring for 3 days at room temperature, the mixture was poured into 15% aq. NaOH solution (500 mL) at 0° C. The precipitate was collected via filtration and washed with water to give dimethyl-(6-nitro-1H-indol-3-ylmethyl)-amine (23 g, 87%).
