Reaction Conditions

Reaction Steps

After 6-amino-3-cyanopyridine (1.0 g, 8.4 mmol) was dissolved in 1-propanol (50 ml) and hydrogen chloride gas was passed into the solution at a temperature of 0°-10° C. for 30 minutes, the reactor was tight sealed for stirring the mixture at 0° C. for 21 hours. After the completion of the reaction, the reaction mixture was concentrated under reduced pressure, and a saturated aqueous sodium hydrogen carbonate solution (50 ml) was added to the concentrated mixture to adjust the pH to alkaline. The mixture was extracted with chloroform (50 ml×3). The chloroform layer was dried over anhydrous sodium sulfate and concentrated under reduced pressure to give a crude product of propyl 6-amino-3-pyridinecarboximidate (1.56 g).
