実験手順
Add sodium ethoxide (1.6 mL of 21% w/v in ethanol, 4.8 mmol) to a solution of 6-chloronicotinonitrile (612 mg, 4.41 mmol) in anhydrous ethanol (15 mL) and heat the reaction at reflux for 3 h. Cool to room temperature and stir overnight under nitrogen atmosphere. Concentrate in vacuo and dissolve the residue into dichloromethane. Wash with saturated aqueous NaHCO3, dry over MgSO4 and concentrate in vacuo to give the desired intermediate as an off-white solid (545 mg, 83%).
