8-Chloro-5-(2-(4-fluorophenyl)prop-1-enyl)-2,3,4,5-tetrahydro-2-methyl-1H-pyrido[4,3-b]indole (100 mg, 0.282 mmol), sodium tertbutoxide (324 mg, 2.948 mmol), palladium acetate (12 mg, 0.049 mmol) and 2-di-tertbutylphosphino-2′-4′-6′-triisopropylbiphenyl (31 mg, 0.0735 mmol) were charged in a reaction bottle which was evacuated and back filled with nitrogen for 5 min. Anhydrous toluene (2 mL) was added under nitrogen atmosphere. Finally, dimethylamine hydrochloride (45.13 mg, 0.564 mmol) was added to the reaction mixture and contents heated at 100° C. overnight. The reaction mixture was filtered, and washed with EtOAc (2×25 mL). The filtrate obtained was concentrated under vacuum and purified on reverse phase chromatography to yield 34 mg of desired compound as the TFA salt. 1H NMR (CD3OD, TFA salt) δ (ppm): 7.78 (s, 1H), 7.58 (m, 2H), 7.38 (s, 2H), 7.10 (t, 2H), 6.90 (s, 1H), 4.70 (m, 1H), 4.40 (m, 1H), 3.80 (m, 1H), 3.58 (m, 1H), 3.28 (s, 6H), 3.10 (m, 2H), 3.05 (s, 3H), 1.80 (s, 3H).
