1-Formulate a reaction mechanism to show how, with excess acetic anhydride ,2-methyl benzisoxazinone might be formed.(Hint: acetylation of the amino group should occur first). How many moles of acetic anhydride are consumed in this reaction?
2-Show how 2-methylbenzisoxazinone is hydrolyzed to N-acetylanthranilic acid. Why is this compound readily hydrolyzed?
