Procedure

To a solution of LiN(TMS)2 (Aldrich, 1.0 M solution in THF, 30 mL, 30 mmol) in THF (30 mL) was added ethyl 4-pyridylacetate (Aldrich, 4.7 mL, 30 mmol)) at 0° C. Methyl iodide (Aldrich, 2.4 mL, 38 mmol) was added 30 min later. After 1 h, the reaction mixture was concentrated in vacuo. The crude product was purified by silica gel chromatography. Mass Spec. m/z+ion 180 (M+1).
