1-Boc-3-piperidinone (5.0 g, 0.0251 mol) in THF (15 mL) was added dropwise to a solution of potassium cyanide (1.8 g, 0.0276 mol) in water (15 mL) at 0-5° C. Acetic acid (1.6 mL, 0.0276 mol) was added and the solution was allowed to warm to room temperature and stir for 1 hr. The mixture was partitioned between water (50 mL) and ethyl acetate (1×150 mL). The organics were washed with 2×50 mL water, 1×50 mL saturated sodium chloride, and dried over Na2SO4. The dried organics were evaporated to obtain 5.5 g of yellow solid. The material was used without purification. MS (ESI) m/z 265 [M+K]+.
