(5 wt%) (1 eq.)[0074] l-(3, 3-Dimethyl-6-nitroindoline-ly)ethanone (Example 5, 50 g), 5% Pd/C (1 g, 50% wet) and THF (200 mL) were charged to a 400 mL hydrogenation reactor. The slurry was degassed with vacuum/hydrogen three times and stirred for 6 h at 60 0C under hydrogen (30 PSI). The resulting mixture was filtered through a thin layer of Celite and the cake was washed with THF (150 mL x 2). The filtrate and washes were combined and concentrated in vacuo, followed by addition of toluene (150 mL). The product was isolated by filtration and the wet cake was washed with D.I. water (100 mL x 2) and 50 mL toluene to afford l-(6-amino-3, 3-dimethyl-indolin-l-yl)ethanone (38.5 g, 94% yield, >99.9 A%, 100 wt%).

With hydrogen;palladium 10% on activated carbon; In tetrahydrofuran; at 50℃; under 2585.81 Torr; for 0.133333h; A Parr hydrogenation unit was charged with l-(3,3-dimethyl-6-nitroindolin-1-yl)- ethanone (450 g, 1.92 mol), THF (1.8 L), and 10% Pd/C (20.3 g). The unit was purged with nitrogen twice then agitated. The unit was pressurized with 50 psi hydrogen and the agitation was continued until absorption ceased. Hydrogen absorption was exothermic. The temperature was maintained below 50 C during the reaction. The reaction was monitored by GC. After 8 min, the unit was purged with nitrogen. The mixture was filtered through a Celite pad and washed the pad with THF (100 mL x 1). The filtrate was concentrated under reduced pressure to 1A total volume and cooled to 0 C. To the mixture was added heptane (800 mL x 1) and the mixture was stirred at 0 C for 45 min. The resulting precipitate was collected by filtration, washed the solid with heptane (150 mL x 1), and dried at 50 C under reduced pressure to give l-(6-amino-3,3- dimethylindolin- 1 -yl)ethanone.
