Reaction Steps

2-[1-Benzyl-4-(1-pyridin-4-yl-cyclopropylmethyl)-piperazin-2-yl]-ethanol. A 250 mL flask was charged with the product obtained above (1.34 mmol, 1.0 equiv.), 2-(1-benzyl-piperazin-2-yl)-ethanol (1.18 g, 5.36 mmol, 4.0 equiv.), and 10 mL acetonitrile. The flask was equipped with a reflux condenser, and then placed into a preheated 100° C. bath. After stirring for 24 h, the solution was diluted with CH2Cl2 and saturated NaHCO3, extracted (2×10% MeOH/CH2Cl2), dried (Na2SO4) and concentrated under reduced pressure. Purification by flash chromatography (SiO2, 3% MeOH/CH2Cl2) provided 310 mg of the product as a yellow oil (0.88 mmol).
