反応手順

A mixture of 1-methyl-3,5-dinitro-2-pyridone (0.8 g, 4.0 mmol), 2,2-dimethyl-cyclopentanone (0.45 g, 4.0 mmol) and ammonia solution (2.0M) in methanol (40 mL) 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 (0.183 g, 24% yield).
