Participants

Reaction Steps

15 mmol of the product obtained in Step C, 16 mmol of vinyl tributyltin and 0.43 mmol of tetrakis(triphenylphosphine)palladium, are heated at 110° C., with stirring, for 3 hours in 30 ml of N-methylpyrrolidinone. After removal of the solvent by evaporation, the residue is taken up in 20 ml of dichloromethane and treated with an aqueous 10% potassium fluoride solution.
