Reaction Steps

5-Bromo-2-fluorobenzonitrile (3.06 g, 15.3 mmol), dichlorobis(triphenylphosphine)palladium(II) (478 mg, 0.681 mmol), and copper(I) iodide (165 mg, 0.866 mmol) were combined in triethylamine (15 mL) under an inert atmosphere of nitrogen. Cyclopropylacetylene (1.8 mL) was added, and the mixture was heated to 60° C. until it turned to a black solid. The mixture was diluted with methylene chloride and washed with 1 N hydrochloric acid. The organic layer was absorbed on silica gel and purified by silica gel chromatography eluting with a gradient of 5-40% ethyl acetate in hexanes to afford the title compound. MS (ESI+) m/z 319.0 (M+H)+.
