Versuchsvorschrift

1-[1-(4-Methoxy-2,3-dimethyl-phenyl)-ethyl]-piperazine (0.02 g, 0.081 mmole) was dissolved in anhydrous toluene and 1N NaOH (1:1) at room temperature. The 4-trifluoromethyl benzoyl chloride (0.013 ml, 0.081 mmole) was added into the reaction mixture. The reaction mixture was stirred at room temperature for 30 minutes. The mixture was washed with 1N NaOH, extracted with EtOAC. The combined organic layers were dried over MgSO4. After removal organic solvent, the residue was purified by SCX column eluted with MeOH and 10% MeOH (NH3) in dichloromethane. (4-Trifluoromethyl-phenyl)-{4-[1-(4-Methoxy2,3-Dimethyl-phenyl)-ethyl]-piperazin-1-yl}-methanone (compound 10) was obtained as a pale yellow oil (0.010 g 30%). Analysis H1 NMR (400MHz, CDCl3): 7.65 (2H, d), 7.495 (2H, d), 7.19 (1H, d), 6.689 (1H, d), 3.764 (3H, s), 3.682 (1H, q), 3.317 (2H, m), 2.506 (6H, m), 2.266 (3H, s), 2.164 (3H, s) 1.286 (3H, d).
