Procedure

At reflux, 10.0 g of 8-bromo-5-nitroquinoline in 68 ml of glacial acetic acid and 34 ml of ethanol were added dropwise to a mixture of 7.75 g of iron powder, 18 ml of glacial acetic acid and 9 ml of ethanol. After stirring for 45 minutes at reflux, the mixture was cooled and filtered through diatomaceous earth. The filtrate was concentrated, taken up in methylene chloride, washed with sodium carbonate solution, dried and concentrated.
