Reaction Steps

To a solution of 5-nitroindole (3.5 g; 21.6 mmol) in DMF (100 ml) was added Cs2CO3 (13.9 g; 42.6 mmol). The mixture thus obtained was stirred 1 h hour at room temperature then 1-bromo-2-methoxyethane (5.9 g; 42.6 mmol) was added dropwise. The resulting mixture was heated to 120° C. under stirring for 4 hours. After cooling, the mixture was poured into water (500 ml) and the crude product was filtered, dried under vacuum to give 1-(2-methoxyethyl)-5-nitro-1H-indole which was used in the following reaction without any further purification.
