実験手順

A mixture of 1-methyl-3,5-dinitro-2-pyridone(2.4 g, 0.012 mole), cyclohexanone (1.18 g, 0.012 mole) and ammonia solution (2.0M, 120 mL) in methanol was refluxed overnight. 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 (2.02 g, 94% yield).
