Procedure

To a solution of 0.5 g (0.89 mmol) 2-(3,5-bis-trifluoromethyl-phenyl)-N-(2-methanesulfonyl-4-o-tolyl-pyrimidin-5-yl)-N-methyl-isobutyramide in 10 ml dioxane 0.25 ml (2.23 mmol) 1-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 H2O. 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 0.37 g (71%) 2-(3,5-bis-trifluoromethyl-phenyl)-N-methyl-N-[2-(4-methyl-piperazin-1-yl)-4-o-tolyl-pyrimidin-5-yl]-isobutyramide as a colorless solid, m.p. 149°151°, MS (ISP): 580.1 (M+H+).
