Versuchsvorschrift

A mixture of 6-bromo-N-[(4,6-dimethyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]-1-(1-methylethyl)-1H-indole-4-carboxamide (0.10 g, 0.240 mmol), 1-methyl-4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-2-pyridinyl]piperazine (0.087 g, 0.288 mmol) and potassium phosphate (tribasic) (0.153 g, 0.721 mmol) in 1,4-dioxane (2 mL) and water (0.5 mL) was degassed with N2 for 10 min, at which time PdCl2(dppf)-CH2Cl2 (0.029 g, 0.036 mmol) was added. The reaction was sealed and heated at 100° C. for 2 h. The reaction was then allowed to cool to RT and sat overnight, at which time it was diluted with EtOAc, filtered through Celite, washed with EtOAc, and concentrated in vacuo. Purification of the residue by column chromatography (12 g Isco GOLD silica column; Gradient B: 5-90%; A: dichloromethane, B: 10% chloroform containing 2 M ammonia in methanol) gave N-[(4,6-dimethyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]-1-(1-methylethyl)-6-[6-(4-methyl-1-piperazinyl)-3-pyridinyl]-1H-indole-4-carboxamide (94 mg, 0.180 mmol, 74.8% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.46 (d, J=6.57 Hz, 6H) 2.12 (s, 3H) 2.17-2.28 (m, 6H) 2.38-2.46 (m, 4H) 3.49-3.57 (m, 4H) 4.37 (d, J=5.05 Hz, 2H) 4.86-4.98 (m, 1H) 5.88 (s, 1H) 6.87 (d, J=3.03 Hz, 1H) 6.93 (d, J=8.84 Hz, 1H) 7.58 (d, J=3.28 Hz, 1H) 7.65 (d, J=1.26 Hz, 1H) 7.87 (s, 1H) 7.98 (dd, J=8.97, 2.65 Hz, 1H) 8.28 (t, J=5.05 Hz, 1H) 8.57 (d, J=2.27 Hz, 1H) 11.55 (s, 1H).
