Versuchsvorschrift

7-Nitro-1H-indole-2-carboxylic acid (371 mg, 3.2 mmol) prepared in Step A was dissolved in N,N-dimethylformamide (10 mL). Triethylamine (0.6 mL, 4.3 mmol), EDC (614 mg, 3.2 mmol) and HOBT (433 mg, 3.2 mmol) were added, 2-chloroethylamine (252.8 mg, 3.2 mmol) was added, and the mixture was stirred for 8 h at room temperature. 1N-hydrochloric acid solution was added, and the reaction mixture was extracted with ethyl acetate, washed with saturated sodium bicarbonate solution, dried over anhydrous magnesium sulfate, and filtered. The filtrate was distilled under reduced pressure to give the title compound.
