The title reaction, carried out in DMF in the presence of triethylamine or potassium carbonate, has furnished the 'expected' 3-amino-2-nitrobenzo[b]thiophenes 2o together with the 'unexpected' 2-amino-3-nitrobenzo[b]thiophenes 3o, thus recalling the situation observed with other weak nucleophiles in
