Synthesis of 5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one derivatives
Veretennikov,Pavlov
, p. 575 - 579 (2013)
The reaction of 2-aminothiazoles with ethyl acetoacetate in acetic or polyphosphoric acid gave a series of 5H-[1,3]thiazolo[3,2-a]pyrimidin-5-one derivatives which were nitrated with a mixture of nitric and sulfuric acid to 6-nitro-5H-[1,3]thiazolo[3,2-a]
