Procedure

A 508 mg portion of (4aR)-(10bR)-4,10b-dimethyl-8-bromo-1,2,3,4,4a,5,6,10b-octahydrobenzo[f]quinolin-3-one, 4 mg of palladium acetate, 20 mg of tri-o-tolylphosphine, 0.34 mL of triethylamine and 5 mL of dimethylformamide were combined in a sealable tube with a stir bar, and the mixture was warmed to 50° under argon. An 0.26 g portion of 4-ethenylisoquinoline was added. Then the vessel was blanketed with argon and sealed and the mixture was heated with stirring at 120° for 20 hours. It was then cooled, and concentrated under vacuum and the residue was purified by chromatography on silica gel, eluting with 5% isopropanol in chloroform. An 0.29 g portion of an oil was obtained, which was recrystallized from ethyl acetate/hexane to obtain the desired product in crystalline form. mp 183°-185°; FDMS 382 M+.
