Reaction Steps

A solution of 1.01 g. (0.005 mole) of 1,2,4-triazine-3,5-dione-6-carboxylic acid hydrazide hydrazine salt in 50 ml. of water, 20 ml. of 1N hydrochloric acid and 70 ml. of N,N-dimethylformamide was cooled to -3° C. A solution of 0.83 g. (0.012 mole) of sodium nitrite in 4 ml. of water was added to the hydrazide solution and the mixture was stirred at -3° C. to -5° C. for 30 minutes to give in solution the acid azide of 1,2,4-triazine-3,5-dione-6-carboxylic acid.
