Reaction Steps

To a solution of 3-hydroxy-2-methylbenzoic acid (5.00 g, 25.3 mmol) in concentrated H2SO4 (98%, 10 mL) was added concentrated HNO3 (63%, 10 mL) dropwise. The mixture was stirred at −40° C. for 10 min. The mixture was poured into ice-water and extracted by EA (3 times). The organic layers were combined, dried over anhydrous Na2SO4. Then the solvent was evaporated in vacuo to afford 3-hydroxy-2-methyl-4-nitrobenzoic acid as a yellow solid, which was used for next step without further purification.
