Reaction Steps

8-Chloro-2-methyl-5-(2-pyridin-4-yl-propenyl)-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (0.100 g, 0.245 mmol), sodium tertbutoxide (0.283 g, 2.948 mmol), palladium acetate (0.010 g, 0.049 mmol) and 2-di-tertbutylphosphino-2′-4′-6′-triisopropylbiphenyl (0.031 g, 0.0735 mmol) were charged in a reaction bottle which was evacuated and back filled with nitrogen for 5 min. Dry toluene (2 mL) was added under nitrogen atmosphere. Finally, di-methylamine hydrochloride (0.040 g, 0.490 mmol) was added and the contents heated at 100° C. overnight. The reaction mixture was filtered and precipitate washed with EtOAc (2×25 mL). The filtrate was concentrated under vacuum and purified by reverse phase chromatography to yield 15 mg of free base. 1H NMR (CD3OD, HCl salt) δ (ppm): 8.90 (d, 2H), 8.38 (d, 2H), 7.99 (s, 1H), 7.80 (s, 1H), 7.56 (m, 2H), 4.50 (m, 2H), 3.90 (m, 1H), 3.70 (m, 1H), 3.38 (s, 6H), 3.22 (m, 2H), 3.18 (s, 3H), 2.16 (s, 3H).
