The downstream synthesis method of this compound is introduced below.<\/p>\n<p>5-Amino-lH-pyrazole-3,4-dicarbonitrile (7.6 g, 57 mmol) was suspended in trimethylorthoformate (60 mL) in a round bottom flask fitted with a stirbar and reflux condenser. The flask was placed in an oil bath and the mixture was heated at reflux overnight. After cooling to rt the following morning, the reaction solution was concentrated under reduced pressure to afford an orange oil. The oil was dried under high vacuum with stirring for 2h. The residue was dissolved in MeOH (25 mL) and cooled under nitrogen in an ice-water bath. A solution of ammonia in MeOH (7.0 M, 65 mL, 460 mmol) was added. The resulting slightly opaque solution was warmed to rt and stirred overnight. The solids produced were isolated by suction filtration, washed with MeOH and dried under suction. The tan powder was transferred to a round bottom flask and dried under high vacuum and used without further purification (6.20 g, 68%, 2 steps).
