Participants

Reaction Steps

A mixture of 6-bromo-4-chloroquinoline (6.52 g, 26.88 mmol; see J. Med. Chem., 21, 268 (1978)), tributyl(vinyl)tin (8.95 g, 28.22 mmol), and tetrakistriphenylphosphine palladium (0) (0.62 g, 0.54 mmol) in 1,4-dioxane (150 mL) was refluxed for 2.0 h, cooled to room temperature, and concentrated in vacuo. The residue was purified by flash chromatography on silica gel (0-4% MeOH:CH2Cl2) to give the title compound (5.1 g) as a pale yellow solid. MS(ES)+m/e 190 [M+H]+. This material was used directly in the next step.
