Reaction Steps

Add cyclohexylacetylene (1.54 mL, 11.6 mmol), dichlorobis(triphenylphosphine)palladium (200 mg, 0.28 mmol), copper iodide (100 mg, 0.53 mmol), and triethylamine (2.0 mL, 14.3 mmol) to a solution of 6-chloronicotinonitrile (1.38 g, 9.9 mmol) in DMF (4 mL). Heat the mixture in a sealed flask for 3 h at 100° C. Cool the mixture to room temperature, dilute with 1:1 hexane/EtOAc (100 mL) and wash with an aqueous 10% sodium chloride solution (3×30 mL). Collect the organic layer, concentrate in vacuo, and purify the residue by silica gel chromatography (90g silica, hexane/EtOAc 95/5 to 85/15 gradient) to obtain the desired intermediate (1.75 g, 83%)
