Procedure

4-Butylamino-2-chloro-3-nitroquinoline (33 g, 0.12 mole, Example 112) was combined with toluene (200 mL) and 5% platinum on carbon (1 g). The mixture was hydrogenated on a Parr apparatus at an initial pressure of 38 psi (2.7 Kg/cm2). When the hydrogenation was complete, the catalyst was removed by filtration and the filtrate was concentrated to provide a brown liquid. The liquid was chilled in an ice bath to provide an orange solid. The solid was collected by filtration, slurried with diethyl ether for 30 minutes then filtered to provide 20 g of the desired product as a tan solid. The structure was confirmed by nuclear magnetic resonance spectroscopy.
