2-(Tri-n-butylstannyl)thiophene → HCID 44351555, compound

Participants

Reaction Steps

Five hundred mg of (4aR)-(10bR)-4,10b-dimethyl-8-bromo-1,2,3,4,4a,5,6,10b-octahydrobenzo[f]quinolin-3-one was combined with 730 mg of 2-(tri-n-butylstannyl)thiophene and 100 mg of bis(triphenylphosphene) palladium chloride in 6 mL of acetonitrile in a screw capped sealable tube. The mixture was flushed with argon for 5 minutes, capped and heated at 90° for 20 h. Upon cooling, the mixture was filtered and the filtrate was concentrated in vacuum. The residue was purified by chromatography on a silica gel column, eluting with ethyl acetate, and the isolated product was recrystallized from ethyl acetate/hexane/chloroform to obtain 167 mg of the desired product. mp 193°-195°. FDMS 311.
