Reaktionsschritte

8-Chloro-2-methyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (20 mg, 0.09 mmol), (2-Bromo-vinyl)-benzene (22 mg, 0.12 mmol), potassium phosphate (50 mg, 0.24 mmol), L-Proline (2 mg, 0.017 mmol), CuI (2 mg, 0.01 mmol) were stirred together in dry DMF (1 mL) at RT and N2 gas was purged into it for 5 min. The reaction mixture was heated in microwave at 100° C. for 5 h and then diluted with water. The desired compound was extracted with EtOAc, organic layer dried on anhydrous sodium sulfate, concentrated under vacuum to obtain crude compound which was purified by RHPLC to obtained 8-Chloro-2-methyl-5-styryl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole as an off-white solid. Yield: 11 mg. 1H NMR (DMSO, TFA salt) δ (ppm): 7.90 (d, 1H), 7.80 (d, 1H), 7.65 (m, 3H), 7.42 (t, 2H), 7.30 (m, 2H), 6.98 (d, 1H), 4.60-4.30 (m, 2H), 4.0 (m, 1H), 3.70 (m, 1H), 3.25 (m, 2H), 3.02 (s, 3H).
