Procedure

A mixture of 34 parts of 1-(4-methyl-3-nitrophenyl)1-butanone, 24 parts of 2-propanol saturated with hydrochloric acid and 400 parts of methanol is hydrogenated at normal pressure and at room temperature with 5 parts of palladium-on-charcoal catalyst 10%. After the calculated amount of hydrogen is taken up, the catalyst is filtered off and the filtrate is evaporated. Water is added to the residue and the whole is alkalized with ammonium hydroxide. The product is extracted with 2,2'-oxybispropane. The extract is dried, filtered and evaporated, yielding 25.5 parts of 5-butyl-2-methylbenzenamine as a residue.
