Conditions

Temperature: 50 °C

Procedure

The compound of step 2 (300 mg, 0.779 mmol), 3-cyano-phenylboronic acid (171 mg, 1.17 mmol), tris(dibenzylideneacetone)dipalladium(0) (214 mg, 0.234 mmol), potassium fluoride (149 mg, 2.57 mmol) and tri-tert-butylphosphonium tetrafluoroborate (136 mg, 0.47 mmol) in a flask were thoroughly flushed with argon, dioxane (3 ml) was added and the mixture was stirred for 2 h at 50° C. The mixture was filtered over silica gel and evaporated to dryness. This residue was purified by RP HPLC (water/ACN gradient) to yield 200 mg of the title compound.
