Versuchsvorschrift

To a solution of 2-methyl-6-nitro-2,3,4,9-tetrahydro-1H-β-carboline (description 1) (1.42 g, 6.13 mmol) in EtOH (300 mL), 570 mg of (5%) Pd/C were added. The mixture was hydrogenated under 20 psi at room temperature for 20 h and filtered through a pad of Celite. The EtOH was evaporated to dryness to yield 1.32 g of 6-amino-2-methyl-2,3,4,9-tetrahydro-1H-β-carboline that were used directly to synthesize compounds of formula I.
