To a solution of 1-[5-nitroindole-2-carbonyl]-4-[3-(1,1-dimethylpropylamino)-2-pyridinyl]piperazine (PREPARATION 67, 1.00 g) in dimethylformamide/methanol (200 ml, 50/50) under nitrogen is added palladium on carbon (10%, 250 mg). The mixture is put under hydrogen (balloon) for 4 hr and nitrogen for 17 hr, filtered through a pad of celite, and concentrated under reduced pressure to give the title compound, NMR (CDCl3) 9.25, 7.66, 7.24, 7.06, 6.88, 6.76, 6.63, 4.58, 4.05, 3.35, 3.14, 1.73, 1.35 and 0.91.
