Reaction Steps
A mixture of 2-[methyl-(2,2,2-trifluoro-acetyl)-amino]-3-nitro-benzoic acid methyl ester (1.7 g, 5.5 mmol) and 5 M aqueous NaOH (5 mL) in THF (10 mL) was stirred at 50° C. for several hours. The mixture was acidified with 4 M HCl and extracted with EtOAc to provide 2-methylamino-3-nitro-benzoic acid. MS m/z: 197.0 (M+H)+.
