Versuchsvorschrift
A twofold stoichiometric excess of 3% hydrogen chloride in dioxane is added to a solution of 1.0 g. of 2-isopropylamino-5-methyl-4H-3,1-benzoxazin-4-one in 20 ml dioxane. Diethyl ether is added until precipitation is complete. The product is filtered, washed with ether, air dried and recrystallized to give 2-isopropylamino-5-methyl-4H-3,1-benzoxazin-4-one hydrochloride.
