Reaction Steps

N-[6-chloro-4-(2,2,2-trifluoro-acetylamino)-9H-β-carbolin-8-yl]-nicotinamide (38 mg, 0.088 mmol, 1 equiv.) was suspended in 5 ml of MeOH and a 2 ml aqueous solution of K2CO3 (121 mg, 0.92 mmol, 10 equiv.) was added thereto. The resulting clear solution was heated at 60° C. for 11 hr. After cooling to RT, fine solids precipitated that were captured by filtration and washed with 10 ml of water to give 2.78 mg (10%) of N-(4-amino-6-chloro-9H-β-carbolin-8-yl)-nicotinamide. 1H-NMR (300 MHz, DMSO-d6): δ 11.32 (s, 1H), 10.56 (s, 1H), 9.26 (s, 1H), 8.82 (d, 1), 8.42 (d, 1), 8.36 (s, 1H), 8.18 (s, 1H), 7.79 (s, 1H), 7.70 (s, 1H), 7.64 (m, 1H), 5.91 (br, 2H). Formic acid standard conditions. DAD RT=1.55 min. M+H=338.
