Procedure
In a manner similar to that of Example 1(c), by reacting 34 g (148 mmol) of 1-bromo-2-ethyl-5-nitrobenzene with 33 g (591 mmol) of iron, and after purification by chromatography on a column of silica eluted with a mixture of heptane and ethyl acetate (90/10), 27 g (89%) of the expected product are obtained in the form of a yellow oil.
