실험 절차

To a solution of N-Boc-3-piperidone (5.00 g, 25.1 mmol) and THF (15 mL) was added KCN (2.34 g, 37.6 mmol) and H2O (15 mL) and the resulting solution was cooled to 0° C. To the resulting homogeneous orange solution was added a solution of NaHSO3 (1.25 g, 37.6 mmol) and H2O (15 mL). The resulting solution was stirred at 0° C. for 1 hour. The solution was twice extracted DCM and the combined extracts were dried by Na2SO4, filtered and evaporated to afford title compound 5.7 g as white solid. MS (m/z): 127 (M+H-Boc)+
