Reaction Steps

1-(4-Bromo-2-nitrophenyl)-1,2,3,4-tetrahydroquinoline (11.6 g, 0.035 mole) was dissolved in benzene (125 ml), and ethanol added (75 ml), followed by 1% platinum-on-charcoal (0.40 g). The mixture was shaken under an initial pressure of 56 psi for 6.5 hours. The mixture was filtered and the filtrate was evaporated at 50° C. under vacuum to provide 10.6 g (100%) of product, as a gum.
