実験手順

Production Example 1 was repeated except that 1-(4-methoxyphenyl)piperazine dihydrochloride, (2-bromoethyl)benzene and tetrahydrofuran were replaced with 5-methoxy-2-(piperazin-1-yl)benzonitrile (599 mg), 3-cyclohexylpropyl methylsulfonate (608 mg) and N,N-dimethylformamide (6.8 mL), respectively, and the resulting crude product was purified on silica gel column chromatograpy (eluent, ethyl acetate: hexane=1:1) to provide 2-[4-(3-cyclohexylpropyl)piperazin-1-yl]-5-methoxybenzonitrile (439 mg).

後処理
