Procedure
Tris(dibenzylideneacetone)dipalladium (0) (57.2 mg, 0.06 mmol) and rac-2,2'-Bis(diphenylphosphino)-1,1'-binaphthyl (78 mg, 0.12 mmol) were added to a mixture of 2-bromo-4-fluorobenzonitrile (250 mg, 1.25 mmol), Cesium carbonate (611 mg, 1.87 mmol) and Piperazine (215 mg, 2.50 mmol) in dioxane (3 mL). Reaction vessel was placed in an oil bath at 90 °C 4pm. LCMS o/n shows several peaks. Larger peak corresponding to displacement of F by piperazine (MW266) than for desired product (205). Discarded
