Yield:-

Reaction Conditions:

with sodium hydroxide in water

Steps:

3 EXAMPLE 3; Bis-aminoguanidinium 3,6-Dinitropyrazolo(4,3-c)pyrazole (AG2-DNPP Salt)
A solution of aminoguanidine carbonate (1.44 g, 10.6 mmol) in 15 mL of H₂O was neutralized with NaOH to yield a white slurry. This was added to a solution of DNPP (1 g, 5 mmol) in a MeOH/H₂O solution (2:1, 12 mL). An orange slurry formed upon addition which was allowed to stir at room temperature overnight. The precipitate was collected by suction filtration and washed with EtOH to yield a light orange powder. (1.70 g, 99%) Recrystallization from 1:1 MeOH/H₂O yielded yellow-orange matted needles; m.p. 181° C.; IR(KBr)3548, 3446, 3409, 3348, 3218, 3163, 3050, 1681, 1654, 1462, 1432, 1370, 1295, 1229, 1207, 1080, 956, 831 cm^-1.
