Several 6-methyl-9-carbamoyltetrahydro-4H-pyrido[l,2-a]pyrimid~-4-ones have been prepared using phosgene iminium chloride. These compounds can exist in equilibrium as the cis (3A) imine$(3B) enaminee trans (3C) imine. 'H, 13C and "N NMR prove that the cis-and trans-imine isomers are predominant in t
