A solution of 6.8 g (22 mmol) (4-isopropyl-phenyl)-(3-methoxy-2-nitro-phenyl)-methanone in 90 ml methanol and 40 ml THF is hydrogenated at normal pressure and rt during 20 h in the presence of 2 g Raney nickel. After filtration and evaporation of the solvent the residue is taken up in ether and (4-isopropyl-phenyl)-(3-methoxy-2-nitro-phenyl)-methanone precipitates by the addition of saturated etheric hydrochloric acid as its hydrochloride.
