Versuchsvorschrift

A mixture of 6.59 g (0.025 moles) of the 4-benzyloxy-3-chloro nitrobenzene (example 4), 4.19 g (0.075 moles) of iron powder, and 12.04 g (0.225 moles) of ammonium chloride in 100 ml of ethanol and 25 ml of water was stirred mechanically and refluxed for half an hour. The reaction was allowed to cool and stir for 1 hour. The mixture was filtered and solids were washed with ethanol. The combined filtrates were taken to dryness in vacuo. This solid was dissolved in methylene chloride and passed through Magnesol. Removal of the solvent from the filtrate in vacuo gave 5.60 g of title compound.
