Versuchsvorschrift

To a stirred suspension of sodium hydride (0.236 g, 5.9 mmol) in dry DMF (5 mL) at 0° C. was added 4-allyl-2,4,8-trimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole (1 g, 3.937 mol, in dry DMF 2 mL). After addition was complete, reaction mixture was stirred at 0° C. for an additional 10 min. 1-(1-Bromomethyl-vinyl)-4-fluoro-benzene (1.09 g, 5.118 mmol) in dry DMF (3 mL) was added dropwise at 0° C. The reaction mixture was stirred at 25° C. for 16 h. The reaction mixture was diluted with ice-water and extracted with EtOAc (2×50 mL). The organic layer was repeatedly washed with water, dried over anhydrous sodium sulfate, concentrated under reduced pressure and the residue purified by chromatography on neutral aluminum oxide (eluting with EtOAc:Hexanes, 1:99) to obtain 700 mg of 4-allyl-5-[2-(4-fluoro-phenyl)-allyl]-2,4,8-trimethyl-2,3,4,5-tetrahydro-1H-pyrido[4,3-b]indole.
