| Abstract: | Conclusions A study was made of the acetylation of 4-hydroxy-6-methyl-1-phenyl-2(1H)-pyridone with acetic acid in presence of polyphosphoric acid and of phosphoryl chloride. The structures of the C- and O-acetyl derivatives obtained were proved by independent synthesis and from IR and UV spectral data.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 9, pp. 1605–1607, September, 1966. |
