Synthesis

1072-98-6

4214-74-8

General procedure for the synthesis of 2-amino-3,5-dichloropyridine from 2-amino-5-chloropyridine: 5500 mL of a solvent mixture of DMF and methanol with a volume ratio of 2.5:1 was added to a 10L three-necked round-bottomed flask, a thermometer was mounted and configured with condensation reflux device, and a magnetic stirrer was started. 2560.8 g of 2-amino-5-chloropyridine and 6118.4 g of N-chlorosuccinimide were added sequentially, and the reaction mixture was stirred at 45 °C for 2.5 hours. The reaction progress was monitored by TLC and GC until the reaction was complete. After completion of the reaction, the solvent was removed by distillation to obtain the crude product, which was purified by recrystallization with ethanol to afford the target compound 2-amino-3,5-dichloropyridine. The product was dried in 70.5% yield and 98.20% purity (GC analysis).
