Reaction Steps

A mixture of 0.57 g of 1-(4-isopropoxy-3-nitrophenyl)-4-methylpiperazine and 65 mg of 10% palladium-on-carbon in 200 ml of ethanol is hydrogenated at 25° C. under 1 bar for 22 h. The mixture is filtered on Clarcel and the Clarcel is rinsed with methanol. The filtrate is concentrated to dryness under reduced pressure and the residue is purified by chromatography on a 25 g silica cartridge, elution being carried out with pure dichloromethane and then successively with 98/2 and 95/5 v/v dichloromethane/methanol mixtures at a flow rate of 30 ml/min, so as to obtain 0.32 g of 2-isopropoxy-5-(4-methylpiperazin-1-yl)phenylamine in the form of a brown solid.
