Versuchsvorschrift

The mixture of 1-(4,4-dimethyl-7-nitro-3,4-dihydroquinolin-1(2H)-yl)ethanone (0.97 g) and Pd/C (10 wt %, 0.20 g) in 10 ml of MeOH was placed under H2 and stirred at RT for 2 h then filtered through a pad of Celite. Removal of the solvents gave 1-(7-amino-4,4-dimethyl-3,4-dihydroquinolin-1(2H)-yl)ethanone as an off-white viscous oil.
