Acetic Acid → HCID 13813702, compound

Participants

Reaction Steps

Iron powder (8.70 g, 156 mmol) was added to a suspension of 2-nitro-5,6-dimethoxybenzonitrile (9.30 g, 44.5 mmol) in an acetic acid (30 ml) and 2-propanol (30 ml) mixture. The mildly exothermic reaction which resulted was allowed to reach 100° and a gentle reflux was maintained for 1 hour with application of heat. Charcoal (10 g) was added, the reaction mixture filtered, and the solid residue obtained was washed with hot 2-propanol (100 ml). The combined filtrates were evaporated to an oily residue which was redissolved in CHCl3 and washed with 5% aqueous NaHCO3 and saturated aqueous NaCl solution. The CHCl3 phase was dried with Na2SO4 and evaporated in vacuo to yield 7.0 g (88.4%) of the target compound as an oil.
