Procedure

A mixture of 1-benzoyl-4-piperidone (2.0 g, 9.8 mmol), tosylmethyl isocyanide (2.5 g, 12.8 mmol) and ethanol (1.0 mL, 17.1 mmol) in 30 mL DME was cooled in an ethanol/ice bath, and potassium tert-butoxide was added at such a rate to maintain the reaction temperature at <10° C. The cold bath was removed, and the reaction was allowed to stir overnight at room temperature. The solids were removed by filtration, rinsed with DME, and the filtrate was evaporated. The residue was dissolved in EtOAc, washed with water and brine, dried (MgSO4), filtered through silica gel, and concentrated to give 2.14 g (66%) of a slightly yellow oil.
