Versuchsvorschrift

To a mixture of 3-Amino-2-carboethoxyindole (572 mg) and triethylamine (400 mg) in methylene chloride (100 mL) was added benzoyl chloride (450 mg). After 30 min at room temperature the reaction mixture was washed with 0.1N HCl, dried over magnesium sulfate and the solvent was removed in vacuo. The residue was triturated with ether to afford 3-Benzamido-2-carboethoxyindole as a white solid.
