YieldReaction ConditionsOperation in experiment
1%; 1%; 50% With hydrogenchloride; water; acetic acid; sodium nitrite; at 0 - 20℃; for 20.0h; General procedure for diazotization of aminopyrazoles 1a-d and aminoimidazoles 2a-c: Aqueous NaNO2 (1.8 mmol, 1 mL) was added to a well-stirred and cooled solution (0-5 C) of pyrazole or imidazole (1 mmol) in a mixture of HCl/AcOH (3:1, 20 mL) over a period of 10 min. The reaction mixture was allowed to warm at room temperature and was stirred for 20 h. The precipitate of pyrazolotriazinone or imidazotriazinone was then filtered off, and the residue was diluted with water (20 mL), extracted with dichloromethane (3 × 30 mL), and dried with anhydrous MgSO4. The resulting solution was concentrated to dryness, and the solid was then subject to chromatographic column separation with dichloromethane and dichloromethane/ethyl acetate in different proportions.
