Participants

Reaction Steps

A solution of 7.49 g 1-(1-Ethoxy-vinyl)-4-Fluorobenzene in 3.6 mL of Pyridine was added at 0° C. to 8.19 g of Trichloroacetyl chloride. The suspension was diluted with 15 ml of dry methylene chloride and stirred at room temperature overnight. The resulting dark brown suspension was concentrated in vaccuo, filtered over a silica gel column with a 9:1 mixture of Heptane and Ethyl acetate as eluant. One obtains after concentration 28 g of a reddish brown oil which was repurified by chromatography on silica gel using a 19:1 mixture of Heptane and Ethyl acetate as eluant. The obtained brown oil (10.15 g) was directly used in the next step.
