摘要：

By the action of 2-aminothiazole, 2-aminopyridines, and 2-aminopyrimidines, respectively, on 4-chloro-3-nitrocoumarin (3) the corresponding 4-heteroarylamino-3-nitrocoumarins 5-7 have been isolated in very good yields. Reactions of coumarins 6 and 7 with either aqueous tetrabutylammonium bisulfate/sodium hydroxide in a two phase system or 5% aqueous sodium hydroxide have been studied.
