Reaction Steps

A mixture of (2-Iodo-5-methanesulfonyl-phenyl)-[4-(4-trifluoromethyl-phenyl)-piperazin-1-yl]-methanone (Example 9; 100 mg, 0.186 mmol), Tributyl-isopropenyl-stannane (CAS: 100073-15-2; 74 mg, 0.223 mmol), Tris(dibenzylideneacetone)dipalladium chloroform complex (15.4 mg, 0.0149 mmol), Triphenylarsine (27 mg, 0.0856 mmol), Copper iodide (3.2 mg, 0.0167 mmol) in N,N-Dimethylformamide (1 ml) was heated at 90° C. for 75 minutes. The mixture was cooled to room temperature and DMF was evaporated under high vacuum. The residue was dissolved in Ethyl acetate and 4mL of a 30% Potassium fluoride solution were added. The mixture was stirred for 30 minutes. Then the aqueous phase was separated and extracted 2 times with Ethyl acetate. The organic phases were combined, washed with water, dried with Na2SO4 ,filtered and evaporated to dryness. The so obtained residue was chromatographed over SiO2 (Heptane/EtOAc 0% to 30% over 15 minutes) to provide the title compound (59 mg, 70% as a yellow solid).
