反応手順
Iron 60 mesh (134.5 g., 2.40 mole), concentrated HCl (37.4 cc), ethanol (630 cc), and water (570 cc) are stirred under nitrogen and the temperature of the mixture is raised to reflux. Then o-propoxynitrobenzene (12.5 g., 0.69 mole), is added at reflux over a period of 5 hrs. and refluxed for 3-4 hrs. Then the mixture is neutralized with concentrated ammonia to a pH of 8-9. The temperature is raised to 30° C., and the reaction mass filtered, 200 cc ether added, the organic layer separated. The product distilled at vapor temperature of 65°-67° C. at 0.05-0.03 mm. yielding 77 g of product (74%).
