実験手順

In step (3) of Reaction Scheme I, a 3-nitroquinolin-4-amine or 3-nitro[1,5]naphthyridin-4-amine of Formula XVIII is reduced to provide a quinoline-3,4-diamine or [1,5]naphthyridine-3,4-diamine of Formula XIX. The reaction can be carried out by hydrogenation using a heterogeneous hydrogenation catalyst such as platinum on carbon. The hydrogenation is conveniently carried out in a Parr apparatus in a suitable solvent such as toluene, methanol, isopropanol, ethyl acetate, or acetonitrile. The reaction can be carried out at ambient temperature.
