Versuchsvorschrift

A solution of 2,8-dimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (0.2 g, 1 mmol), (3-bromo-phenyl)-dimethyl-amine (600 mg, 3 mmol), K3PO4 (636 mg, 3 mmol), L-Proline (69 mg, 0.6 mmol) and CuI (57 mg, 0.3 mmol) in dry DMF (4 mL) was stirred at 150° C. for 16 h. The reaction mixture was cooled to RT, diluted with water and extracted with EtOAc. The organic layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to afford crude material, which was purified by column chromatography using neutral alumina and 10% EtOAc-Hexane to yield [3-(2,8-dimethyl-1,2,3,4-tetrahydro-pyrido[4,3-b]indol-5-yl)-phenyl]-dimethyl-amine as an off white solid (11 mg). 1H NMR (Oxalate salt, CD3OD) d (ppm): 7.40 (t, 1H), 7.30 (s, 1H), 7.10 (d, 1H), 7.86 (d, 1H), 6.64 (m, 2H), 4.58 (m, 2H), 3.64 (m, 2H), 3.16 (s, 3H), 3.08 (m, 2H), 2.96 (s, 6H), 2.42 (s, 3H).
