Product 1

HCID 28000032-Chloropyridine-4-carbonyl chloride

Procedure

2-Chloroisonicotinic acid (707 mg, 4.49 mmol) was suspended in thionyl chloride (10 mL), followed by stirring under heating and reflux for 7 hours. The reaction mixture was concentrated under reduced pressure to afford 2-chloroisonicotinoyl chloride.
