Reaction Steps

A stirred solution of 2.68 grams (0.01 mole) of 4-chloro-2-ethoxycarbonyl-7-nitroindole, 80 mL of acetic acid, and 15 mL of water was heated to 65° C., and 18.3 grams (0.048 mole) of iron powder was slowly added during a 20 minute period. Upon completion of addition, the reaction mixture was allowed to cool to 25° C. where it stirred for one hour. After this time, the reaction mixture was poured into water, and the resulting mixture was filtered through diatomaceous earth. The filter cake was washed thoroughly with ethyl acetate. The organic layer was dried with magnesium sulfate and filtered. The filtrate was concentrated under reduced pressure a residue. The residue was purified by column chromatography, yielding 0.4 gram of title compound. The NMR spectrum was consistent with the proposed structure.
