반응 단계
To a solution of 1-methyl-3,5-dinitro-2-pyridone (8.0 g, 40 mmol) in methyl alcohol (20 mL) was added dropwise 3-methyl-2-butanone (5.1 mL, 48 mmol), followed by ammonia solution in methyl alcohol (10.0 g, 17%, 100 mmol). The reaction mixture was heated at 70° C. for 2.5 h under atmospheric pressure. The solvent was removed under vacuum and the residual oil was dissolved in CH2Cl2, and then filtered. The filtrate was dried over Na2SO4 and concentrated to afford 2-isopropyl-5-nitro-pyridine (1.88 g, 28%).
