Reaction Steps

A mixture of N-(diethylaminoethyl)-2-methoxy-3-methyl-5-nitrobenzamide (4.25 g), platinum oxide (425 mg) and methanol (85 ml) is shaken in a hydrogen stream. After absorption of hydrogen stops, the reaction mixture is filtered to remove the catalyst. The filtrate is concentrated under vacuum and the residue is chromatographed on a column of alumina, which is eluated with methylene chloride to methylene chloride-2% methanol. The eluate is concentrated under vacuum and the residue is washed with isopropyl ether to give N-(diethylaminoethyl)-5-amino-2-methoxy-3-methylbenzamide (2.38 g) as crystals melting at 56° to 57° C.
