Reaction Steps
To a degassed mixture of 6-chloro-2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (100 mg, 0.5 mmol), sodium tert-butoxide (576 mg, 6.0 mmol), palladium acetate (22.4 mg, 0.1 mmol) and 2,4 di-tert-butylphosphino-2′,4′,6′-triisopropyl biphenyl (63.0 mg, 0.15 mmol) was added dry toluene (2 mL). After stirring for 5 min, benzylmethylamine (0.09 mL, 0.7 mmol) was added to the reaction mixture, which was stirred at 100° C. for 16 h. The reaction mixture was filtered and residue washed with EtOAc. The filtrate was concentrated under reduced pressure to afford crude material, which was purified by reverse phase HPLC to yield benzyl-methyl-(2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indol-6-yl)-amine (50 mg). 1H NMR (Freebase, CDCl3) δ (ppm): 7.80 (bs, 1H), 7.38 (m, 4H), 7.28 (m, 1H), 7.10 (s, 1H), 7.0 (t, 1H), 6.78 (d, 1H), 4.28 (s, 2H), 3.70 (s, 2H), 2.86 (m, 4H), 2.78 (s, 3H), 2.58 (s, 3H).
