HCID 20300399, compound → N~1~-(Pentan-3-yl)benzene-1,2-diamine

Participants

Reaction Steps

In a 2 liter hydrogenator is placed 2.5 g. of 10% palladium on carbon catalyst, 800 ml. of absolute alcohol and 250 g. of o-nitro-N-(1-ethylpropyl) aniline. Hydrogen is introduced and the reduction is complete in about 21/2 hours. The reaction is exothermic and the temperature subsides as the reaction goes to completion. The catalyst is removed by filtration and the ethanol is evaporated to yield a nearly quantitative yield (214 g.) of product as a dark oil. A pure sample is obtained by vacuum distillation, b.p. 2.0 mm Hg=125°-126° C.
