1-(3-Methoxyphenyl)-2-methyl-4-nitrobenzene(23.4 gm, 96 mmol) was dissolved in a mixture of ethanol and ethyl acetate (3:1, 470 mL) and hydrogenated over 10% palladium on charcoal (2.3 gm) at 3 bar and 20° C. for 2 h. The mixture was filtered through Arbocel filter aid, washing with ethyl acetate. The filtrate was concentrated under reduced pressure to give 4-amino-1-(3-methoxyphenyl)-2-methylbenzene (20.8 gm, 100%) as a pinkish-brown oil.
