실험 절차

A mixture of 6-fluoro-3-(4-piperidinyl)-1,2-benzisoxazole (3.27 g, 14.8 mmoles), K2CO3(3 g), 1-[4-(3-bromopropoxy)phenyl]ethanone (4.5 g, 17.5 mmoles) in acetonitrile (60 ml) was heated at reflux for 4 hr. The solvent was removed. The residue was dissolved in dichloromethane (300 ml) and washed with water and brine, then dried over MgSO4. The crude product from the evaporated solution was purified by flash chromatography (SiO2. 60 g; eluted with 1% methanol in dichloromethane, methane 1liter). The purest fractions were combined and gave 2.8 g, 48% of 1-[4-[3-[4-(6-fluoro-1,2benzisoxazol-3-yl)-1-piperidinyl]propoxy)phenyl]ethanone, m.p.=111°-112° C.
