실험 절차
A mixture of 4-chloro-6-isopropyl-3-nitro-1H-pyridin-2-one (700 mg, 3.23 mmol) in 6-7 μL of 7 N NH3 in MeOH is stirred at 100° C. in a sealed tube for 1.5 h. After cooling, the reaction mixture is concentrated in vacuo. The residue is suspended in H2O, filtered, washed with H2O, and dried, yielding 4-amino-6-isopropyl-3-nitro-1H-pyridin-2-one. 1H NMR (DMSO-d6, 300 MHz) δ 10.96 (br s, 1H), 8.15 (br s, 2H), 5.70 (d, J=0.9 Hz, 1H), 2.58 (sept, J=6.9 Hz, 1H), 1.11 (d, J=6.9 Hz, 6H) ppm.
