실험 절차
To a solution of 4-piperidylmethanol (1.0 g, 8.7 mmol) and HCHO (2 mL, 25 mmol, 37% in H2O) in CH3CN was added NaCNBH3 (0.5 g, 12.5 mmol). The resulting mixture was stirred for 1 h and filtered. The filtrate was concentrated and the residue was distilled (105° C., 40 torr) to give the title intermediate.
