実験手順

443.0 g. (1.5 moles) of N-(3-methoxycarbonyl-5-nitrobenzoyl)-glycine methylamide in 5.5 l. of dioxane is agitated for 2 hours at room temperature with the addition of 3.3 l. of 0.5 N sodium hydroxide solution. Thereafter, 400 ml. of water is added to the reaction mixture, the dioxane is distilled off under vacuum, and the acid is precipitated with concentrated hydrochloric acid, vacuum-filtered, washed free of salt with water, and dried under vacuum at 70° C.
