Adding a certain compound to certain chemical reactions, such as: 58607-90-2, name is Ethyl 5-oxo-4,5-dihydro-1H-pyrazole-3-carboxylate, belongs to pyrazoles-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 58607-90-2, Formula: C6H8N2O3
a. PREPARATION OF ETHYL 5-{[r£r-BUTYL(DiMETHYL)siLYL]oxY}-lH- PYRAZOLE-3-CARBO Al). [00552] Tert-butyldimethylsilyl chloride (6.05 g, 40.15 mmol) and imidazole (2.92 g, 42.82 mmol) were added to a stirred solution of ethyl 5-oxo-4,5-dihydro-lH-pyrazole-3- carboxylate (4.18 g, 26.76 mmol) in ACN (90 mL). The mixture was stirred at room temperature for 30 minutes, then diluted with water and extracted with AcOEt. The organic layer was separated, dried (Na2S04), filtered and the solvents evaporated in vacuo to yield ethyl 5- {[tert4outyl(dimethyl)silyl]oxy}-lH-pyrazole-3-carboxylate (3.2 g, 44% yield) as a yellow solid, that was used in the next step without further purification.
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, Ethyl 5-oxo-4,5-dihydro-1H-pyrazole-3-carboxylate, other downstream synthetic routes, hurry up and to see.
