Procedure

A mixture of [4-(6-chloropyridazin-3-yl)piperazin-1-yl]-(2-trifluoromethylphenyl)-methanone (0.075 g, 0.202 mmol), 2-phenylethanol (0.025 g, 0.202 mmol) and sodium hydride (0.010 g) in 5 mL of toluene was stirred at room temperature for 1 hour, and then refluxed overnight. The reaction mixture was cooled to room temperature, added 20 mL of water, and then extracted with ethyl acetate. The organic layer was washed with water, dried over anhydrous sodium sulphate, concentrated in vacuo. The residue was purified by column chromatography to yield the title compound as a white solid (58 mg, 62.9%). 1H NMR (400 MHz, CDCl3) δ 7.73, 7.61-7.64, 7.53-7.56, 7.36, 7.22-7.30, 7.20-7.24, 7.02, 6.86, 4.64, 3.91-3.98, 3.57, 3.48-3.52, 3.32, 3.11.
