A solution of 1-cyclopentyl-pent-4-yn-1-one (0.33 g, 2.2 mmol) from example F(7), Step 2,4-iodo-2,5-dimethyl-phenol (0.54 g, 2.2 mmol), copper (I) iodide (33 mg, 0.18 mmol), trans-dichlorobis(triphenylphosphine)palladium (II) (63 mg, 0.09 mmol), and diisopropylamine (2.2 mL) in DMF (2.2 mL) was heated to 100° C. for 30 minutes. The reaction was cooled to room temperature and diluted with 10 mL of EtOAc. The resulting slurry was filtered, and the mother liquor was concentrated to a black oil. The oil was then purified by flash chromatography to give the desired product (112 mg, 19% yield).
