Procedure

Under an argon atmosphere, 22.3 g. electrolyte iron, 64 ml. ethanol and 53.4 ml. water were mixed together. To the resultant stirred mixture was added in one portion 1.88 ml. concentrated hydrochloric acid and the resulting mixture heated to reflux. 4.1 g. of the nitro ether prepared in Example I was added to this hot stirred mixture. The addition was made in portions of near reflux temperatures. The mixture was then refluxed for 30 minutes and 1.26 ml. of 50% sodium hydroxide solution was added. This mixture was filtered while hot through dicalite. The filtrate was concentrated in vacuo and then taken up in 200 ml. of methylene chloride, washed with two 500 ml. portions of water and four 100 ml. portions of saturated sodium carbonate solution. The washed mixture was dried over magnesium sulfate and evaporated in vacuo to yield 34 g. of product having a m.p. of 90°-91° C. The product was identified as the title product by IR and NMR analyses.
