2-Amino-3,5-dichloropyridine Use and Manufacturing
To a 10 L round bottom three-necked flask was added 5500 ml of a 2.5: 1 mixture of DMF and methanol in a volume ratio of 2.500 ml, inserted into a thermometer and equipped with a condensing reflux device, the magnetic stirrer was started and 2560.8 g of 2-amino- Pyridine, N-chlorosuccinimide 6118.4 g, and the reaction was stirred at 45 ° C for 2.5 hours.TLC and GC were determined to complete the reaction.The crude product was distilled off to give the crude product and recrystallized from ethanol to give pure product 2-amino-3, 5-dichloropyridine. After drying, the yield was 70.5percent and the purity was 98.20percent (GC).
