N-(4-甲基-5-硝基-1,3-噻唑-2-基)乙酰胺 | N-(4-methyl-5-nitro-thiazol-2-yl)-acetamide | 21478-97-7 | C6H7N3O3S | 201.206 |
1-Chloro-3-methyl-2-butanone and 2-amino-4-isopropylthiazole have been synthesized. The mononitration of 2-aminothiazole and five alkyl-2-aminothiazoles in the 2-amino group has been carried out with absolute nitric acid in concentrated sulphuric acid at low temperatures ranging from 0° to −10°. 2-Nitramino- and alkyl-2-nitramino-thiazoles are crystalline, stable compounds. The dinitration of some alkyl-2-aminothiazoles under the same conditions lead to the formation of alkyl-2-nitramino-5-nitrothiazoles. The rearrangement of 2-nitraminothiazole to 2-amino-5-nitrothiazole was studied in the presence of mesitylene for the first time.
