Reaction Conditions

Reaction Steps

A mixture of 1.24 g (5 mmol) of 2-(4-iodophenyl)ethanol, 0.62 g (5.25 mmol) of 7-azaindole, 2.33 g (11.0 mmol) of potassium phosphate, 0.082 g (1.0 mmol) of N,N′-dimethylethylenediamine and 0.095 g (0.50 mmol) of cuprous iodide in 4 ml of toluene is heated at 80° C. overnight with thorough stirring under an argon atmosphere. The mixture is cooled to ambient temperature and diluted with 150 ml of ethyl acetate and 50 ml of water. After the phases have settled and been separated, the organic phase is washed with 25 ml of water and 25 ml of saturated aqueous sodium chloride solution. It is dried over sodium sulphate and evaporated to dryness. The residue is purified by chromatography on silica gel, eluting with a 70/30 then 60/40 and 50/50 mixture of cyclohexane and ethyl acetate, to give 1.05 g of product in the form of an oil.
