Abstract

Triethylammonium 5-[(2,2-dimethyl-4,6-dioxo-1,3-dioxan- 5-ylidene)(methylthio)methyl]-1,3-dimethylpyrimidine- 2,4,6-trionate (6) is obtained as red-orange stable crystals by reaction of 5-[bis(methylthio)methylene]-2,2-dimethyl- 1,3-dioxane-4,6-dione (5) with 1,3-dimethylbarbituric acid (2) in the presence of triethylamine in excellent yield. The crystal structure of 6 confirms the negative charge to be localized at the barbituric-acid ring in its enolate form.
