Procedure

To a solution of 2 g (16 mmol) of 2-hydroximinohomopiperidine (Maybridge) in 20 mL of methylene chloride (CH2Cl2) was added 2.5 g (16 mmol) of 1,1′-carbonyldiimidazole (CDI). This was stirred at 25° C. for six days. This solution was diluted with CH2Cl2, washed with water, dried (MgSO4), filtered and concentrated to afford 2.2 g (89% yield) of the title compound as a white semi-solid.
