with dihydrogen peroxide in sodium hydroxide;
Steps:
25 EXAMPLE 25
4 ml of a 30% hydrogen peroxide solution are added dropwise at room temperature to 3.8 g (16.7 mmol) of 6-chloro-4-nitro-indoline-2,3-dione in 60 ml of sodium hydroxide solution. The mixture is stirred for 2 hours at room temperature, acidified to pH 2 to 3 with 4N hydro-chloric acid, filtered and dried. 3.18 g (87.8% of theory) of 4-chloro-6-nitro-anthranilic acid having a melting point of 202°-205° are obtained.
