Procedure

A mixture of N,N-bis(2-methoxyethyl)-3-nitrobenzamide (4.11 g) and palladium on charcoal (411 mg) in ethyl acetate (41 ml) was hydrogenated under 1 atmospheric pressure to hydrogen for 1 hour at ambient temperature. The catalyst was removed by filtration and washed with ethyl acetate, and the volatiles were removed in vacuo. The residue was purified with column chromatography eluting with dichloromethane-methanol to give 3-amino-N,N-bis(2-methoxyethyl)benzamide (3.62 g) as an oil.
