Reaction Steps

To a solution of 3-hydroxy-4-methyl-2-nitrobenzoic acid (365 g, 1.85 mol) in DMF (3280 mL) were added K2CO3 (524.4 g, 3.80 mol) and MeI (788 g, 5.55 mol) in one portion. Then the reaction mixture was stirred at room temperature overnight. TLC(CH2Cl2/MeOH=3:1) indicated the reaction was complete. Water (9 L) was added to the reaction mixture and the mixture was extracted with EtOAc (3 L×2). The combined organic layers were washed with 1 N aq. NaOH (1 L×2) and brine, dried over anhydrous Na2SO4 and concentrated in vacuo to give the title compound (395 g, 94.7%) as a light yellow solid.
