300 mg of 1-(3-Bromo-4-trifluoromethyl-benzoylamino)-4-methyl-cyclohexanecarboxylic acid methyl ester, 267 mg of 2,6-difluoro-4-methoxyphenylboronic acid, 65 mg of tris(dibenzylideneacetone)di-palladium(0), 96 mg of bis(2-dicyclohexylphosphinophenyl)ether, 453 mg of K3PO4, and 1 g of molecular sieve 4 Å were added to 10 ml of toluene. The mixture was made oxygen-free by passing argon through it. Then, the mixture was kept at 160° C. under microwave irradiation for 2 h. Then, 267 mg of 2,6-difluoro-4-methoxyphenylboronic acid, 65 mg of tris(dibenzylideneacetone)di-palladium(0), 96 mg of bis(2-dicyclohexylphosphinophenyl)ether were added and the mixture was kept at 160° C. under microwave irradiation for 2 h. The mixture was cooled to room temperature and 100 ml of EA added. The mixture was then washed twice using 20 ml of a saturated aqueous Na2CO3-solution each. The organic layer was dried using MgSO4 and the solvent evaporated. Chromatography on silica gel using EA/HEP 1:5 yielded 16 mg of the title compound, viscous oil.
