A novel preparation method for 2-amino-3,5-dinitro-6-chloropyridine (4) and its derivatives was described starting from cheap and easily available 2,6-dichloropyridine (1). Compound 4 was obtained by nitration, amination and again nitration reaction, followed by reacting with several nucleophilic reagents, such as ammonia, sodium azide to form 2-amino-3,5-dinitropyridine-6-substituted derivatives 57, respectively. The results showed that this synthetic route had the advantages of easy-obtained raw materials, simple work-up and high purity product.

Key words: preparation, 2,6-dichloropyridine, 2-amino-3,5-dinitro-6-chloropyridine, nucleophilic substitution
