Versuchsvorschrift

The 1-(bromoacetyl)-5-(methyloxy)-6-nitro-2,3-dihydro-1H-indole (4.0 g, 12.7 mmol) was dissolved in 50 mL of dichloromethane, then K2CO3 (4.4 g, 31.7 mmol) and N-methyl-2-(methyloxy)ethanamine (1.4 g, 15.2 mmol) in 10 mL dichloromethane were added, the reaction was stirred at RT overnight. The reaction mixture was diluted with 100 mL of water, the organic solvents were washed with water (2×100 mL), and dried over Na2SO4. The solvent was removed under reduced pressure and the resulting residue was dissolved in 10 mL of EA, 25 mL of MeOH and 15 mL of THF, then 0.8 g 10% Pd/C was added, and the reaction was stirred at RT overnight under a balloon of H2 pressure. The catalyst was removed via filtration and the solvent was evaporated under reduced pressure to yield the 1-({methyl[2-(methyloxy)ethyl]amino}acetyl)-5-(methyloxy)-2,3-dihydro-1H-indol-6-amine as a white solid (3.1 g, 89%). 1HNMR (400 MHz, DMSO-d6) δ ppm: 2.28(s, 3H), 2.62 (t, J=5.77 Hz, 2H), 2.94 (t, J=8.24 Hz 2 H), 3.19 (s, 3H), 3.25(s, 2H), 3.41 (t, J=5.77 Hz, 2 H), 3.68(s, 3H), 4.04 (t, J=8.33 Hz,2H), 4.61 (s, 2H), 6.67 (s, 1 H), 7.52 (s, 1 H).
