Reaction Steps

N-[6-chloro-4-(2,2,2-trifluoro-acetylamino)-9H-β-carbolin-8-yl]-nicotinamide (41 mg, 0.092 mmol, 1 equiv.) was suspended in 5 ml of MeOH and a 2 ml aqueous solution of K2CO3 (127 mg, 0.92 mmol, 10 equiv.) was added thereto. The resulting clear solution was heated at 60° C. for 16 hr and then allowed to cool to RT. Additional water was added producing fine solids that were captured by filtration, washed once with 10 ml of 5% MeOH in Et2O, and dried under high vacuum to give 18 mg of N-(4-amino-6-chloro-9H-β-carbolin-8-yl)-2-methyl-nicotinamide as powdery yellow solids (56% yield). 1H-NMR (300 MHz, DMSO-d6): δ 11.18 (s, 1H), 10.41 (s, 1H), 8.62 (d, J=3.6, 1H),), 8.32 (s, 1H), 8.20 (s, 1H), 8.11 (d, J=7.5, 1H), 7.91 (s, 1H), 7.79 (s, 1H), 7.43 (m, 1H), 5.91 (br, 2H), 2.66 (s, 3H). Formic acid standard conditions. DAD RT=1.63 min. M+H=352.
