The solution of 3-[4-chloro-6-(4-fluorophenyl)-2-(trifluoromethyl)pyrimidin-5-yl]benzenesulfonamide (0.1 g, 0.24 mmol, prepared according to the procedure described above in preparation 4, Step 2a), in acetonitrile (2 ml) was treated with piperazine (0.104 g, 1.203 mmol) and the reaction mixture was stirred overnight at room temperature. Subsequently the reaction mixture was poured into ice-cold water and was extracted with ethylacetate (25 ml). The organic layer was washed with water, brine solution and then evaporated to obtain the title compound. 1H-NMR (DMSO-d6) δ: 2.58 (s, 4H), 3.19 (s, 4H), 7.03-7.14 (m, 4H), 7.32 (d, 1H), 7.41 (brs, D2O exchangeable, 2H), 7.46-7.50 (t, 1H), 7.72 (s, 1H), 7.73 (d, 1H). MS m/z: 482.1 (M++1).
