Versuchsvorschrift

A mixture of 9-nitro-5,6-dihydro-benzo[f]quinoline (1.90 g), 10% palladium on carbon (0.20 g), and methanol (10 mL) is shaken under hydrogen atmosphere (3 bar) at room temperature for 3 h. The catalyst is then separated by filtration and the filtrate is concentrated to give an oil that is submitted to the next reaction without further purification. Yield: 1.67 g (crude); Mass spectrum (ESI+): m/z=197 [M+H]+.
