Synthetic Route of 1280210-79-8, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 1280210-79-8, name is tert-Butyl 4,6-dihydropyrrolo[3,4-c]pyrazole-5(2H)-carboxylate, This compound has unique chemical properties. The synthetic route is as follows.
2D (3.5 g, 16.7 mmol) was dissolved in tetrahydrofuran (35 mL)Cooled to 0 C,60% sodium hydride (1.0 g, 25.4 mmol) was added,After reaction for 30 minutes, methylsulfonyl chloride (2.9 g, 25.4 mmol) was added and reacted for 1 hour.The reaction mixture was quenched with water (10 mL) and extracted with ethyl acetate (50 mL x 2). The organic layers were combined and the organic layer was dried over anhydrous sodium sulfate and concentrated. The residue was purified by silica gel column chromatography (petroleum ether / Ethyl acetate (v / v) = 1: 1) to give 2E as a white solid (2.1 g, yield 44%).
The chemical industry reduces the impact on the environment during synthesis tert-Butyl 4,6-dihydropyrrolo[3,4-c]pyrazole-5(2H)-carboxylate. I believe this compound will play a more active role in future production and life.
