A degassed mixture of 6-iodo-3-(4-piperidin-1-ylmethyl-phenyl)-9H-dipyrido[2,3-b;4′,3′-d]pyrrole (100 mg, 0.21 mmol), 1-methyl-5-(trimethylstannyl)-1H-1,2,3-triazole (158 mg, 0.64 mmol) and bis(triphenylphosphine)palladium(II) dichloride (15 mg, 0.021 mmol) in N,N-diisopropylethylamine (0.74 mL, 0.43 mmol) in 1,4-dioxane (1.7 mL) was heated at 100° C. for 1 h. The cooled reaction mixture was diluted with DCM (20 mL) and methanol (2 mL) and washed with water (15 mL). The organic phase was separated, dried over sodium sulfate, filtered and evaporated in vacuo to afford a residue that was purified by preparative HPLC (20-60% MeCN in water (0.1% ammonium hydroxide) over 30 min, 35 mL/min) to afford the title compound as a pale yellow solid (20 mg, 20%). 1H NMR (DMSO-D6, 400 MHz): 12.47 (s, 1H), 9.05 (s, 1H), 9.04 (d, J=2.2 Hz, 1H), 8.96 (d, J=2.2 Hz, 1H), 8.78 (s, 1H), 8.18 (s, 1H), 7.77 (d, J=8.1 Hz, 2H), 7.45 (d, J=8.1 Hz, 2H), 4.37 (s, 3H), 3.50 (s, 2H), 2.35 (s, 4H), 1.52 (m, 4H), 1.41 (m, 2H). LCMS (method D): RT=8.04 min, M+H+=424.
