Participants

Reaction Steps

3-Bromo-2-cyano-5-nitropyridine (0.4g, 1.75 mmol) and iron powder (0.51g, 8.8 mmol, 325 Mesh) were reacted as described in example 762D. The crude solid obtained by trituration with ether was purified by SiO2 Prep-TLC using 4:1 CH2Cl2/ether as eluent to give compound 769A (0.16 g, (65%) as an off-white solid. HPLC: 100% at 1.77 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 197.93 [M+H]+.
