실험 절차

A mixture of bromoacetonitrile (0.70 mL, 10 mmol), 4-(3-methoxyphenyl)piperidine (1.74 g, 9.1 mmol) and K2CO3 (1.3 g) in MeCN was stirred at room temperature for 3 days. The reaction mixture was partitioned between CH2Cl2 and H2O, and the organic extract was dried (Na2SO4). The solvent was then removed in vacuo to afford [4-(3-methoxyphenyl)-1-piperidinyl]acetonitrile as an amber oil (2.03 g, 97%): MS (DCl) m/z 231 (MH+). Anal. Calcd. for C14H18N2O.0.5 H2O: C, 70.27; H, 8.00; N, 11.71. Found: C, 70.12; H, 7.67; N, 11.87.
