Procedure

5-Bromo-6-methoxybenzo[b]furan-2,3-dicarboxylic acid (D12) (0.85 g, 2.7 mmoles) was heated to its melting point (~270° C.) for 15 mins (CO2 evolution). The mixture was allowed to cool and the resulting black residue extracted with ethyl acetate. The organic solution was then filtered and the filtrate evaporated to dryness to give the title compound (D13) (0.65 g, 89%)
