Versuchsvorschrift

1-(1-methylethoxy)-2-nitrobenzene, 45.26 g (0.25 mol) is dissolved in 500 ml of methanol, 4 g Raney nickel is added and the mixture is exposed to hydrogen gas until the required amount of hydrogen is absorbed. The methanol solution is filtered and concentrated in vacuo and the residue distilled to give 35.7 g (94.4%) of 2-(1-methylethoxy)benzenamine; bp 100-102 (at 4 mm).
