Reference of 398495-65-3, The chemical industry reduces the impact on the environment during synthesis 398495-65-3, name is 5-tert-Butyl 1-ethyl 3-aminopyrrolo[3,4-c]pyrazole-1,5(4H,6H)-dicarboxylate, I believe this compound will play a more active role in future production and life.
To a mixture of 3-amino-4,6-dihydro-pyrrolo[3,4-c]pyrazole-l,5-dicarboxylic acid 5- tert-butyl ester 1-ethyl ester (244 mg, 0.75 mmol), dry tetrahydrofuran (30 mL) and N,N-diisopropylethylamine (0.75 mL, 4.4 mmol) was added 3-[(tetrahydro-pyran-4-yl)- (2,2,2-trifluoro-acetyl)-amino]-isonicotinoyl chloride (1.1 mmol). The mixture was stirred at 45C for Ih, then evaporated to dryness, diluted with dichloromethane (100 mL), washed with saturated sodium hydrogenocarbonate (100 mL), dried over sodium sulfate and avaporated to dryness affording the crude title compound that was used as such for the next step
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 5-tert-Butyl 1-ethyl 3-aminopyrrolo[3,4-c]pyrazole-1,5(4H,6H)-dicarboxylate, other downstream synthetic routes, hurry up and to see.
