Procedure
To a solution of 0.22 g (0.38 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-(2-methanesulfonyl-4-o-tolyloxy-pyrimidin-5-yl)-N-methyl-isobutyramide in 10 ml dioxane 0.106 ml (0.96 mmol) I-methylpiperazine was added. The reaction mixture was stirred for 16 hrs. After evaporation of the solvent, the residue was distributed between 50 ml CH2Cl2 and 50 ml sat. NaHCO3-solution. The aqueous layer was extracted with 50 ml CH2Cl2, the combined organic layers dried (MgSO4), filtered and evaporated. The residue was purified by chromatography (SiO2, CH2Cl2/MeOH/NH4OH 110:10:1) to give 0.11 g (48%) 2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-N-[2-(4-methyl-piperazin-1-yl)-4-o-tolyloxy-pyrimidin-5-yl]-isobutyramide as a white foam, MS (ISP): 596.2 (M+H)+.
