Reaktionsschritte

NaH (300 mg; 60%) is added to the solution of methyl nicotinoylacetate (896 mg, 5 mmol) in THF (15 mL) at 0° C. under argon atmosphere. The reaction mixture is stirred for 15 minutes at the temperature and benzyl bromide (0.36 mL) is added. The reaction mixture is heated at reflux overnight. The reaction mixture is poured into iced 1N HCl and extracted with EtOAc three times. The combined organic extract is washed with brine and dried over MgSO4. Concentration under reduced pressure gives the residue which is purified over column chromatography to afford methyl 2-benzyl-nicotinoylacetate intermediate (389 mg).
