Participants

Reaction Steps

To a solution of 1H-indole-6-carboxylic acid methyl ester (1.0 g, 5.7 mmol) and 3-nitrobenzyl bromide (1.48 g, 6.8 mmol) in DMF (15 mL) was added K2CO3 (1.6 g, 11.4 mmol). After stirring at room temperature for 16 hr, the solution was diluted with ethyl acetate (100 ml) and washed with water (3×50 ml). The organic layer was dried (MgSO4), filtered and concentrated. The remaining residue was recrystallized with ethyl acetate/hexane to provide 1.34 g (76% yield) of 1-(3-nitrobenzyl)-1H-indole-6-carboxylic acid methyl ester as light orange crystals.
