Reaction Conditions

Reaction Steps

To the solution of methyl 2-formyl-3-[2-(methyloxy)-5-pyrimidinyl]propanoate (2 g, 8.92 mmol) and potassium tert-butoxide (3.00 g, 26.8 mmol) in ethanol (15 mL) was added neat N-nitroguanidine (1.857 g, 17.84 mmol). The reaction mixture was stirred at 120° C. for 1 h. After removing the solvent, 5 mL water was added to dissolve the solid, and HCl (conc.) was used to adjust pH˜3. The precipitate was collected to provide the title compound (1.8 g, 72.5% yield). LCMS: rt=0.96 min, [M+H+]=279.1
