4-Bromobenzoyl chloride → 1-(4-Bromophenyl)-2-(3-fluoro-4-methylthiophenyl)ethanone

Participants

Reaction Steps

To the mixture of 4-bromobenzoyl chloride (10.81 g, 49.26 mmol), zinc (4.40 g, 67.24 mmol) and tetrakis(triphenylphosphine)palladium(0) (2.99 g, 2.586 mmol in DME (250 mL) was added dropwise the solution of 4-(bromomethyl)-2-fluoro-1-(methylsulfanyl)benzene (12.16 g, 51.72 mmol) in DME (120 mL) at room temperature. After 2.5 hour, the mixture was filtered through celite, the filtrate was evaporated, diluted with ethyl acetate (300 mL), washed with water (100 mL), brine (100 mL), dried over sodium sulfate, and concentrated in vacuo. The residue was washed with ethyl acetate-isopropylether, to give the subtitle compound (12.16 g, 73% yield) as a solid.
