실험 절차

Crude 2-(4-iodo-2-pyridyl)butanenitrile (270 mg, 0.9923 mmol) was added to a solution of iodoethane (309.6 mg, 158.8 μL, 1.985 mmol) and bis(trimethylsilyl)azanide (sodium ion (1)) (992.3 μL of 1 M, 0.9923 mmol) in toluene (2 mL) at 0° C. The solution was stirred at 0° C. for 10 minutes. Reaction mixture was diluted with water and the product extracted with dichloromethane (×3). Organic extracts were combined, dried over MgSO4, filtered and concentrated in vacuo. (297.8 mg, assumed 100% yield). LC/MS m/z 301.02 [M+H]+
