Reaction Steps
A mixture of 2-(3-cyclohex-1-enyl-4-nitro-phenyl)-malonic acid dimethyl ester (as prepared in the previous step, 200 mg, 0.600 mmol), iron powder (168 mg, 3.00 mmol) and NH4Cl (321 mg, 6.00 mmol) in 6 mL of ethanol was stirred at 80° C. for 16 h. After cooling to RT, the mixture was treated with 30 mL of H2O and extracted with EtOAc (3×20 mL). The combined organic layers were dried (Na2SO4) and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (30% EtOAc-hexane) to give 129 mg (71%) of the title compound as a faint yellow oil: Mass spectrum (ESI, m/z): Calcd. for C17H21NO4, 304.2 (M+H). found 304.1.
