실험 절차
2-Chloro-3-iodo-5-nitropyridine (0.25g, 0.88 mmol) was reacted with iron powder (0.25g, 4.4 mmol) in the manner described in example 762D. Removal of the solvent in vacuo gave compound 765C (0.172g, 77%), as a golden yellow solid. HPLC: 100% at 2.32 min(YMC S5 ODS column) eluting with 10–90% aqueous methanol containing 0.2% phosphoric acid over a 4 min gradient monitoring at 220 nm. MS (ES): m/z 255.03 [M+H]+.
