반응 단계
According to the same manner as in Example 4, except that the flask was changed to 300 ml flask, laurylpyridinium chloride was not used, 103 g of water was added, and that amounts of toluene, phosgene and 4-chloroanthranilic acid were changed to 34 g, 40 g and 35 g, respectively, 35.6 g of 7-chloroisatoic anhydride (purity: 73.8%) was obtained. The yield was 67% and the volume efficiency was 9 g/100 ml.
