The heat resistant high explosive 2,6-bis(picrylamino)-3,5-dinitropyridine is readily prepared in good yield by first reacting 2,6-diaminopyridine with picryl chloride in a polar, aprotic solvent such as N,N-dimethylformamide, in the presence of sodium fluoride and then nitrating the resultant intermediate 2,6-bis-(picrylamino)pyridine.
