実験手順
0.202 g (0.002 mol) of 4-hydroxypiperidine and 0.55 g (0.0022 mol) of 4-bromobenzyl bromide were dissolved in 5 ml of dimethylformamide and stirred at room temperature for 2 hrs. The solvent was distilled off and the residue was taken up in dichloromethane and washed with sat. bicarbonate solution and sodium chloride solution. The organic phase was dried over sodium sulfate and concentrated. 0.54 g (100%) of 1-(4-bromo-benzyl)-piperidin-4-ol was obtained as a colorless oil. MS: me/e (% basic peak)=271, 269 (C12H16BrNO30 , 73, 76), 270, 268 (79, 70), 171, 169 (99, 100), 114 (64), 100 (60).
