Reaction Steps

prakt. Chem., [2], 30 (1884), 467 et seq., and J. org. Chem., 13 (1948), 347 et seq. and 24 (1959), 1,214 et seq. disclose that isatoic anhydride reacts with aqueous ammonia to give anthranilamide and o-ureidobenzoic acid. The reaction of 5,7-dichloroisatoic anhydride with ammonia gives 6,8-dichlorobenzoyleneurea (J. org. Chem., 3 (1938), 414 et seq., and 12 (1947), 743 et seq.), whilst other chlorine-substituted isatoic anhydrides give only moderate yields of chlorinated anthranilamides (J. Org. Chem., 26 (1961), 613 et seq.).
