Versuchsvorschrift
A 50 ml round-bottom flask with magnetic stirrer was charged with 6-chloro-7-ethylsulfanyl-8-nitro-9H-β-carboline (85.0 mg, 0.28 mmol) in 10 ml anhydrous ethanol. To the resulting orange mixture at RT was added 0.33 M aqueous ammonium chloride (2.0 ml, 0.66 mmol) and iron powder (680 mg, 12.2 mmol). The reaction mixture was heated to 60° C. and stirred vigorously for 20 hr. Next, the mixture was cooled to RT, diluted with ethyl acetate (15 ml), and activated charcoal (180 mg) was added. The resulting mixture was filtered through a pad of celite and the filtrate was concentrated to afford 77.8 mg of 6-chloro-7-ethylsulfanyl-9H-β-carbolin-8-ylamine as a yellow solid (>99%). 1H-NMR (300 MHz, CD3OD, ppm) δ 8.94 (1H, s) 8.33-8.29 (1H, m) 8.21-8.18 (1H, m) 7.73 (1H, s) 2.85 (2H, q) 1.21 (3H, t). LCMS (ammonium acetate standard method) retention time=2.13 min. (M+=278; M=276).
