Reaction Steps

A 5.00 g portion of 4-hydrazinobenzoic acid was suspended in 50 ml of ethanol, and 5.6 ml of 3-pentanone and 2.7 ml of sulfuric acid were added, followed by stirring at 85° C. for 24 hours. After evaporation of ethanol under a reduced pressure, water was added to the residue under ice-cooling, followed by stirring at the same temperature for 30 minutes. The resulting solid was collected by filtration and then washed with water to obtain 6.34 g of ethyl 2-ethyl-3-methyl-1H-indole-5-carboxylate as a light brown solid.
