Procedure

Using the method of Example 17, 2-bromo-3-(2-fluorophenyl)-4-methoxy-7-benzofuranacetic acid is reacted with dinitrogen tetroxide to provide 3-(2-fluorophenyl)-4-methoxy-2-nitro-7-benzofuranacetic acid. Recrystallization of the acid from benzene provides yellow crystals, m.p. 185°-195° C.
