Reaction Steps

A mixture of compound 1 (1.08 g, 1.5 mmol), bis(triphenylphosphine)palladium(II) chloride (21 mg, 0.03 mmol), copper(I) iodide (11 mg, 0.06 mmol) and p-aminophenylacetylene (176 mg, 1.5 mmol) in 10 mL of triethylamine was deaerated with nitrogen and kept at 40° C. for 1.5 h. The mixture was diluted with 40 mL of chloroform, washed with water and dried with sodium sulfate. The solution was evaporated in vacuo and the product was obtained as a yellow oil.
