Versuchsvorschrift

1,2-Didodecanoxy-4-nitrobenzene (10 g, 20.4 mmol) was then dissolved in ethanol (100 ml) , followed by addition of hydrazine (4ml) and graphite (8 g). The mixture was then refluxed for 24 hours and filtered. The filtrate was given a hexane/water work-up and the hexane fraction was dried over MgSO4 and evaporated to produce 1,2-didodecanoxy-4-amino benzene as white solid (8.9 g, 95%). 1H NMR (CDCl3) d 7.02(s, Ph, 1H) 6.96 (d, Ph, 1H), 6.69 (d, Ph, 1H), 3.97 (m, OCH2, 4H), 2.0-0.8 (m, alkyl ).
