Procedure

A solution of 1.2 g (3.8 mMol) 2-(3,5-bis-trifluoromethyl-phenyl)-2-methyl-propionyl chloride and 0.5 ml dichloromethane were added dropwise over 15 minutes at 0° C. to a solution of 1.0 g (3.5 mMol) methyl-(6-morpholin-4-yl-4-o-tolyl-pyridin-3-yl)-amine and 0.85 ml (4.9 mMol) N-ethyl-di-isopropylamine in 7.0 ml dichloromethane. The reaction mixture was stirred 2.5 hours at 0° C., poured onto 8 ml deionized water and stirred further 30 minutes at room temperature. The phases were separated and the aqueous phase extracted with dichloromethane. The organic extracts were washed with deionized water, aqueous sodium hydroxide 2% and aqueous sodium bicarbonate 5%, dried (Na2SO4) and concentrated under reduced pressure. The residue was crystallized from ethanol at −20° C. to yield 1.27 g (64%) 2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-N-(6-morpholin-4-yl-4-o-tolyl-pyridin-3-yl)-isobutyramide as a white powder. Concentration of the mother-liquors gave 0.77 g of a slowly crystallizing brown oil which can be further purified.
