Reaktionsschritte

4.50 g (20.0 mmol) 4,5-dimethoxy-1,2-dinitrobenzene was taken into 50.0 mL EtOH/8.4 mL AcOH mixture. To this was added 4.00 g powdered iron (O). The reaction was heated to an oil bath temperature of 70° C. overnight. The reaction was allowed to cool to room temperature and was poured into 400 mL H2O. Aqueous layer was extracted several times with diethyl ether. Organic layers were dried over magnesium sulfate and evaporated under reduced pressure to give 4.73 g orange solid as a mixture of starting material and product. This solid was purified over silica gel (30% DCM in hexanes) to give the title compound 86A as an orange solid (1.15 g, 5.80 mmol).
