To a solution of 1.20 g (4.74 mmol) [6-chloro-4-(2-chloro-phenyl)-pyridin-3-yl]-methyl-amine and 1.43 g (5.68 mmol) 2-(3,5-dichloro-phenyl)-2-methyl-propionyl chloride in 20 ml toluene 1.27 g (10.42 mmol) 4-dimethylaminopyridine was added and the resulting solution stirred at 120° for 48 h. After cooling to ambient temperature, the solution was poured into 100 ml 0.5 N NaHCO3-solution and extracted three times with 50 ml CH2Cl2. The combined organic layers were dried (Na2SO4), filtered and evaporated. The residue was purified by flash-chromatography (SiO2, hexanes/ethyl acetate 4:1) to give 1.90 g (85%) of the title compound as a white solid.
