Versuchsvorschrift

To a mixture of 6-bromo-1-(1-methylethyl)-1H-indole-4-carboxylic acid (0.71 g, 2.52 mmol), 3-(aminomethyl)-4,6-dimethyl-2(1H)-pyridinone (0.575 g, 3.77 mmol), 1-hydroxy-7-azabenzotriazole (0.514 g, 3.77 mmol), and EDC (0.724 g, 3.77 mmol) in dimethylsulfoxide (20 mL) was added quickly N-methylmorpholine (1.107 mL, 10.07 mmol) via syringe. The solids slowly dissolved and the reaction was maintained at RT overnight. The reaction was slowly poured into ice-water (300 mL), stirred for 10 min, then allowed to sit for 10 min. The solids were filtered and washed with water (100 mL), airdried for 15 min, then dried in vacuum oven at 45° C. for 4 h to give 6-bromo-N-[(4,6-dimethyl-2-oxo-1,2-dihydro-3-pyridinyl)methyl]-1-(1-methylethyl)-1H-indole-4-carboxamide (0.82 g, 1.871 mmol, 74.4% yield). 1H NMR (400 MHz, DMSO-d6) δ ppm 1.39-1.46 (m, 6H) 2.09-2.15 (m, 3H) 2.21 (s, 3H) 4.32 (d, J=5.05 Hz, 2H) 4.82 (quin, J=6.63 Hz, 1H) 5.88 (s, 1H) 6.86 (d, J=3.28 Hz, 1H) 7.51 (d, J=1.77 Hz, 1H) 7.62 (d, J=3.28 Hz, 1H) 7.92 (s, 1H) 8.31 (t, J=4.93 Hz, 1H) 11.55 (br. s., 1H).
