Participants

Reaction Steps

The product from Example 10E (30 mg, 0.084 mmol), (2R,5R)-2,5-dimethylpyrrolidine hydrochloride (50 mg, 0.5 mmol) (purchased from Toronto Research Chemicals, TRC), 75 mg of potassium carbonate and 75 mg of potassium iodide in 5 mL of 2-butanone were heated at 80° C. for 72 hours. The mixture was allowed to cool to ambient temperature, filtered and the filtrate was evaporated under reduced pressure. The residue was purified by HPLC chromatography (C18 reverse phase Water's 25 mm module prep column, 10 to 95% acetonitrile/0.1% TFA in water, 10 minute linear gradient, flow rate 40 mL/minute) to provide the title compound (70% yield).
