Reaction Steps

To 3-chloroisonicotinic acid (413 mg, 2.62 mmol) was added thionyl chloride (5 mL, 68.5 mmol). The reaction mixture was stirred at room temperature for about 20 hours. The solution was concentrated under reduced pressure and the residue was dried under high vacuum for 1 hour to give 3-chloro-isonicotinoyl chloride.
