Reaction Steps

SOCl2 (0.6 mL) was added dropwise to anhydrous MeOH (10 mL) at 0° C. The mixture was stirred at this temperature for 0.5 h, then 3-hydroxy-2-nitrobenzoic acid (0.6 g, 3.2 mmol) was added to the mixture. The resulting mixture was heated at reflux for 4 h. TLC (petroleum ether:ethyl acetate=1:1) showed the reaction was complete. The resulting mixture was concentrated in vacuo to give the title compound (0.63 g 100%) as a brown solid.
