Versuchsvorschrift
A mixture of 1.8 g. of 4-(2-phenoxyethoxy)-2-nitroaniline and 0.3 g. of 5% of palladium-on-charcoal catalyst in 200 ml. of methanol is hydrogenated under ambient conditions. After the uptake of hydrogen is complete, the mixture is filtered and 1,2-diamino-4-(2phenoxyethoxy)benzene is isolated from the filtrate by evaporation.
