Reaktionsschritte

Using a procedure analogous to that described for the starting material in Example 57, ethyl(4-bromo-2-nitrophenyl)acetate (26 g, 90 mmol) was treated with iron in acetic acid. The product thus obtained was recystallised from ether/isohexanes to give 6-bromooxindole (8.2 g, 42%).
