In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact. 1280210-79-8, name is tert-Butyl 4,6-dihydropyrrolo[3,4-c]pyrazole-5(2H)-carboxylate belongs to pyrazoles-derivatives compound, it is a common compound, a new synthetic route is introduced below. category: pyrazoles-derivatives<\/a><\/p>\n

A mixture of (1R,2R)-N1,N2-dimethylcyclohexane-1,2-diamine (25 uL, 0.158 mmol), copper (I) iodide (4.0 mg, 0.021 mmol), potassium phosphate tribasic (69.7 mg, 0.328 mmol), tert-butyl 4,6-dihydro-2H-pyrrolo[3,4-c]pyrazole-5-carboxylate (42.7 mg, 0.204 mmol) and [(3R,3aR,6R,6aS)-3-(1-allyl-6-chloro-5-iodo-imidazo[4,5-b]pyridin-2-yl)oxy-2,3,3a,5,6,6a-hexahydrofuro[3,2-b]furan-6-yl]oxy-tert-butyl-dimethyl-silane (84 mg, 0.145 mmol) in dioxane (1.0 ml) was degassed (3\u00d7) and placed under nitrogen before being heated to 100 C. After 6 hours, the reaction mixture was diluted with EtOAc (30 ml), washed with water (20 ml), brine (10 mL), dried over MgSO4, filtered, and evaporated under reduced pressure to give an oil. The oil was purified on preparative silica plates (1\u00d71000 u developed with 1:1 EtOAc\/hexanes). The resulting solid (86.4 mg, 0.131 mmol) was dissolved in TFA (1.0 mL) and DCM (1.0 mL) and was stirred at room temperature. After 1 hour, the reaction mixture was evaporated to give an oil, and which was lyophilized from ethanol and benzene to give the title compound as a solid. LC-MS: calculated for C26H35ClN6O4Si 558.22 observed m\/e: 559.27 (M+H)+ (Rt 1.15\/2 min).<\/p>\n

The synthetic route of 1280210-79-8 has been constantly updated, and we look forward to future research findings.<\/p>\n
