Procedure

To a mixture of Preparation 221 (9.35 g, 65.80 mmol), piperidine (0.65 ml, 6.58 mmol), methyl cyanoacetate (5.80 ml, 65.80 mmol) and potassium carbonate (0.91 g, 6.58 mmol) in isopropyl alcohol (120 ml) was added potassium cyanide (4.30 g, 65.80 mmol). The reaction mixture was stirred at room temperature for 18 h and then concentrated in vacuo. The residue was partitioned between hydrochloric acid (1M) and ethyl acetate and the two layers were separated. The aqueous layer was extracted with ethyl acetate and the combined extracts were washed with brine, dried (MgSO4) and concentrated in vacuo.
