Reaction Conditions

Reaction Steps

A solution of ethyl (4-{[(2-chloro-5-nitrophenyl)carbonyl]amino}phenyl)acetate (2.27 g, 6.3 mmol) in EtOH (20 ml) was heated at 50° C. A 20% aqueous solution of acetic acid (10 ml) was added followed by iron (6 eq, 37.6 mmol, 2.1 g). The mixture was heated at 80° C. for 30 minutes. On cooling the mixture was filtered through celite washing with EtOH. Solvent evaporated in vacuo. Residue taken up in EtOAc and aqueous sodium bicarbonate. Layers separated, aqueous layer extracted with EtOAc (×2). Organic layers combined and washed with brine, dried over magnesium sulphate and evaporated. The residue was purified by column chromatography (Biotage SP4, 100 g silica column) eluting with 25-75% ethyl acetate in hexanes to afford the title compound as a light yellow oil (1.8 g). MS (ES+) m/z 333 [M+H]+ (C17H1735ClN2O3). 1H-NMR (400 MHz, d6-DMSO) δ 1.18 (3H, m), 3.61 (2H, s), 4.05 (2H, m), 5.47 (2H, s), 6.65 (2H, m), 7.12 (1H, d, J 8.4), 7.22 (2H, d, J 8.4), 7.64 (2H, m).
