Versuchsvorschrift

1-(4-Chlorobutyl)-4-methylpyridin-2(1H)-one (0.99 g, 4.96 mmol) from Example 1.1, 2-tert-butyl-4-piperazin-1-yl-6-(trifluoromethyl)pyrimidine (1.36 g, 4.71 mmol; prepared as described in DE 19735410) and triethylamine (1.51 g, 14.87 mmol) in 25 ml of dimethyl sulfoxide were stirred at 100° C. for 5 hours. Water was then added to the reaction mixture, and the aqueous mixture was extracted twice with tert-butyl methyl ether. The organic phase was extracted three times with a saturated aqueous sodium chloride solution and three times with a 5% aqueous citric acid solution. The aqueous phase was then made alkaline and extracted three times with tert-butyl methyl ether. The combined organic phases were dried over Na2SO4 and, after removal of the desiccant by filtration, concentrated. The resulting oily residue (1.99 g) was purified by chromatography on silica gel (eluent: CH2Cl2/CH3OH: 96.5:3.5), resulting in 1.29 g of the title compound.
