By reacting N-substituted-2-isatinic acids with nitrous acid, indazolols, N-nitroso-N-substituted anthranilic acids and the esters of said acids with the above mentioned indazolols were obtained through disproportionation of the N-nitroso-N-substituted-isatinic acids.
通过使N-取代的2-异丁二酸与亚硝酸反应,吲哚并得到N-亚硝基-N-取代的-N-亚硝基-N-取代的邻氨基苯甲酸和所述的酸与上述的吲哚并的酯。异丁酸。
