실험 절차

To a solution of 3-iodo-2-methyl-5-nitropyridine (125 mg, 0.4734 mmol) in ethanol (3 mL) was added acetic acid (0.50 mL, 8.8 mmol) and iron powder (140 mg, 2.6 mmol). The reaction was heated at 85° C. for 30 minutes and was diluted with EtOAc, water, and saturated Na2CO3. Then it was filtered and extracted with EtOAc and the organic extracts were washed with water, saturated NaCl, dried (MgSO4) and stripped in vacuo. 1H NMR (400 MHz, CDCl3): δ 7.96 (d, 1H), 7.44 (d, 1H), 3.57 (br s, 2H), 2.61 (s, 3H); MS (ES) (M+H)=235.
