Procedure

A 40 mL round bottomed vial was charged with 2-(methylthio)pyrimidine-4-carbaldehyde (4) (771 mg, 5 mmol), imidazolidine-2,4-dione (500 mg, 5 mmol, 1.0 equiv.), and piperidine (400 μL, 4 mmol, 0.8 equiv.) in ethanol (20 mL, 0.25 M). The reaction mixture was heated to 80° C. and shaken for 20 h. The resulting yellow precipitate was isolated by filtration and washed with ethanol (1×20 mL) and dried in vacuo to afford (Z)-5-((2-(methylthio)pyrimidin-4-yl)methylene)imidazolidine-2,4-dione (5a) as a yellow solid (565 mg, 1.18 mg theoretical, 48%). LC-MS m/z 237 (M+1). The same procedure can be used to prepare 5b or 5c by replacing imidazolidine-2,4-dione with 1-benzylimidazolidine-2,4-dione or 1-methylimidazolidine-2,4-dione respectively.
