Participants

Reaction Conditions

Reaction Steps

A solution of 2-fluoro-4-iodoaniline (2.37 g, 10 mmol) in toluene (50 mL) was treated with tetrakis(triphenylphosphine)palladium (0.578 g, 0.5 mmol), tributylvinyltin (3.5 mL, 12 mmol) and a catalytic amount of 2,6-di-tert-butyl-4-methylphenol. After being heated at 100° C. for 1 h, the reaction mixture was filtered through celite and the filtrate was concentrated in vacuo. The residue was purified by flash column chromatography on silica gel using EtOAc:hexanes (1:5) as eluant to afford 2-Fluoro-4-vinylaniline (20-1, LJO-324, 1.275 g, 93%) as a yellow oil.
