Reaction Steps

309 mg 2-Bromo-4-{2,2,2-trifluoro-1-[4-methyl-2-(6-trifluoromethyl-pyridin-3-yl)-thiazol-5-yl]-ethoxymethyl}-benzonitrile (derived from 2,2,2-Trifluoro-1-[4-methyl-2-(6-trifluoromethyl-pyridin-3-yl)-thiazol-5-yl]-ethanol and 2-Bromo-4-bromomethyl-benzonitrile according to the method described in example 30), 32 mg tricyclohexylphosphine, 148 mg cyclopropylboronic acid and 470 mg K3PO4 mono hydrate were dissolved in a mixture of 4 ml toluene and 0.4 ml water. The reaction mixture was purged with argon, then 130 mg palladium (II) acetate were added. The reaction mixture was stirred at 100° C. for three hours. The cooled reaction mixture was diluted by addition of 100 ml ethyl acetate and filtered through a celite pad. The filtrate was washed twice with 25 ml water, then dried over MgSO4. The solvent was removed in vacuo. The resulting residue was purified by reversed phase HPLC to obtain 185 mg 2-Cyclopropyl-4-{2,2,2-trifluoro-1-[4-methyl-2-(6-trifluoromethyl-pyridin-3-yl)-thiazol-5-yl]-ethoxymethyl}-benzonitrile.
