Reaction Steps
A mixture of 1-methyl-3,5-dinitro-2-pyridone (0.6 g, 3.0 mmol), tetrahydrothiopyran-4-one (0.35 g, 3.0 mmol) and ammonia solution in methanol (2.0 M, 30 mL) was refluxed for 6 h. The solvent was removed in vacuo and the residue was dissolved in ethyl acetate. The soluble portion was flash chromatographed over silica gel (eluent: 90:10 v/v ethyl acetate-hexane)to give a yellow solid (0.586 g, 99% yield).
