Procedure
3-Carbomethoxy-5-nitrobenzyl methanesulfonate (300.0 g, 1.04 mol) and sodium azide (81.0 g, 1.25 mol) were suspended in DMF (1700 ml) and stirred at room temperature for 5 hours. The reaction was diluted with ethyl acetate (2000 ml), washed with 1000 ml portions of H2O (2×) and saturated NaCl (1×), dried (MgSO4), and concentrated under reduced pressure. The resulting amber syrup was dried under vacuum at 40° C. to yield the title compound as a tan solid (226.5 g, 92%). 1H NMR (CDCl3): 8.60 (s, 1H), 8.26 (s, 1H), 8.20 (s, 1H), 4.52 (s, 2H), 3.88 (s, 3H); MP=44°-46° C.
