実験手順
Thionylchloride (3.87 g, 32 mmol) is added dropwise at rt to a mixture of 2-chloro-4-methylamino-5-nitro-benzoic acid (5.00 g, 22 mmol) and 45 mL MeOH and it is stirred at reflux overnight. The mixture is cooled to rt and the precipitate is collected by filtration and dried. Yield: 5.01 g. MS m/z: 245 [M+H]+.
