反应步骤
450 ml of 2N NaOH are initially taken and 75.6 g (0.317 mol) of 2-methyl-3-nitro-6-acetamidobenzoic acid are added. The reaction mixture is then warmed to 95° C. and is stirred at this temperature for one hour. After cooling to 10° C., it is acidified by addition of 425 ml of 2N HCl, and the precipitate which deposits is filtered off with suction, washed with water and dried under reduced pressure at 50° C.
