Reaction Steps

A solution of N3-isopropyl-1H-pyrazole-3,5-diamine (0.231 g, 1.85 mmol) and sodium nitromalonaldehyde monohydrate (0.307 g, 1.95 mmol) in water (20 mL) was heated to 100° C. overnight. The reaction mixture was cooled to room temperature, and the pH was adjusted to about 6 with acetic acid. The resulting solids were collected by filtration, washed with water and dried in vacuo to give N-isopropyl-5-nitro-1H-pyrazolo[3,4-b]pyridin-3-amine (0.243 g, 59%). m/z (APCI-neg) M−1=220.3.
