Procedure

To a solution of 3.29 g (5.23 mmol) 2-(3-chloro-pyridin-2-yl)-5-trifluoromethyl-2H-pyrazole-3-carboxylic acid [2-(bicyclopropyl-1 -ylcarbamoyl)-4-iodo-6-methyl-phenyl]-amide in 50 ml tetrahydrofuran is added 1.19 g (6.25 mmol) Cul, 0.30 g tetrakis(triphenylphosphine) palladium and 2.78 g (31.0 mmol) CuCN. The mixture is heated 1 h at 80° C. and turns dark green. After cooling down, the mixture is filtered on Hyflo and evaporated. The residue is dissolved in 15 ml DMF and poured into 100 ml water containing 5 g NaHCO3. After 30 min stirring, the crystals are filtered, washed with water and a mixture of hexane/acetone (1:3) to afford 2.8 g of the title compound.
