Versuchsvorschrift

N-(8-amino-6-chloro-9H-β-carbolin-4-yl)-2,2,2-trifluoro-acetamide (90 mg, 0.274 mmol, 1 equiv.) and 2-methylnicotinic acid (40 mg, 0.329 mmol, 1.2 equiv.) were dissolved in 1.5 ml of anhydrous pyridine under N2. EDCI (84 mg, 0.438 mmol, 1.6 equiv.) was added in one portion and the reaction mixture was stirred at room temperature 2 hours. The reaction was quenched and treated following the preceding protocol to obtain 38 mg (32%) of N-[6-chloro-4-(2,2,2-trifluoro-acetylamino)-9H-β-carbolin-8-yl]-nicotinamide. 1H-NMR (300 MHz, DMSO-d6): δ 11.89 (br, 1H), 10.73 (s, 1), 9.28 (s, 1), 8.97 (s, 1), 8.84 (d, 1), 8.43 (d, 1), 8.37 (s, 1), 7.85 (s, 1), 7.76 (s, 1), 7.67 (m, 1). Formic acid standard conditions. DAD RT=1.94 min. M+H=434.
