실험 절차

Phosphorus oxychloride (86.9 ml) was dropwise added to a mixture of 6-acetoxymethyl-2-pyridinecarboxamide (93.0 g) and N,N-dimethylformamide (74.2 ml) in ethyl acetate (930 ml) under ice-cooling with stirring and the mixture was stirred at ambient temperature for 4 hours. The reaction mixture was added to a water and adjusted to pH 8 with potassium carbonate. The separated organic layer was washed with brine, dried over magnesium sulfate and evaporated to give 6-acetoxymethyl-2-cyanopyridine (84.0 g) as an oil.
