4-Chloro-5-iodo-7-((2-(trimethylsilyl)ethoxy)methyl)-7H-pyrrolo[2,3-d]pyrimidine (50 mg, 0.12 mmol) was dissolved in 140 μl tetrahydrofuran and 160 μl triethylamine. Ethynylbenzene (16 μl, 0.15 mmol), bis(triphenylphosphine)palladium(II) dichloride (9 mg, 0.01 mmol) and copper(I) iodide (5 mg, 0.02 mmol) were added and the mixture was stirred at room temperature during 2 h. The reaction was poured into a 4% aqueous solution of sodium bicarbonate and extracted twice with ethyl acetate. The organics were combined and washed with water, brine, dried over sodium sulphate, filtered and evaporated under reduced pressure. The residue was purified using SP1® Purification System (0% to 15%, hexane-ethyl acetate) to give 45 mg (95% yield) of the title compound.
