WebSep 30, 2005 · The downfield shift of the NH signal testifies to the interaction of the NH group proton with the oxygen atom of the carbonyl group of the substituent at C4. However, in this case the strong intramolecular NH--O=C hydrogen bonding also confirms the presence in solution of the tautomeric form B ( Figure 5 ). WebThe predicted spectral data suggest that the shift from the enol to the keto tautomer should be accompanied by a red shift in the absorption spectra and up field of the tautomeric proton in 1 H NMR. The absorption spectra of favipiravir in toluene, chloroform and acetonitrile are shown in Supplementary Figure S1.
