実験手順

The title compound was prepared by reduction of a nitro group by catalytic hydrogenation as follows. Into a 500 mL Parr shaker bottle was placed 4.0 g of the N-[2-(3-fluorophenyl)-6-nitro-4-quinolinyl]-N,N-dimethylamine along with 150 mg of a catalyst consisting of 5% palladium on calcium carbonate support. To this was added 150 mL of ethanol, followed by application of a 50 psi hydrogen atmosphere. The reaction was shaken for 18 hr then the hydrogen atmosphere was replaced by nitrogen. The catalyst was removed by filtration, and the solution concentrated. The residue was taken up in ethyl acetate, washed with 5% sodium hydroxide solution, then the organic layer was dried over Na2SO4, filtered and concentrated. The extract was recrystallised from methylene chloride and hexane to give 2.8 g (77%) of the product.
