Tributylvinyltin → HCID 19603510, compound

Participants

Reaction Steps

A mixture of 8-benzyloxy-2-methyl-4-(trifluoromethanesulfonyloxy)quinoline (300 mg), vinyltributyltin (263 mg), tetrakis(triphenylphosphine)palladium (0) (43.6 mg) and lithium chloride (96 mg) in 1,4-dioxane (6 ml) was refluxed for three hours and then left at ambient temperature overnight. The mixture was diluted with ethyl acetate and was added silica gel (70-230 mesh, 5 g) and stirred at ambient temperature for half an hour. The silica gel was removed by filtration and the filtrate was concentrated in vacuo. The residue was chromatographed on a silica gel column eluting with ethyl acetate-n-hexane (1:4, V/V) to give a solid. This solid was crystallized from diisopropyl ether to give 8-benzyloxy-2-methyl-4-vinylquinoline (110 mg) as pale yellow solid.
