Adding a certain compound to certain chemical reactions, such as: 36216-80-5,Benzo[d]isoxazol-3-amine, 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 36216-80-5,36216-80-5
1 ,2-Benzoxazol-3-amine (802 mg, 5.98 mmol) was dissolved in a mixture of anhydrous dichloromethane (4 ml_) and anhydrous pyridine (1 .5 ml_, 19 mmol). To this mixture was added, drop-wise, a solution of ethyl malonyl chloride (1.00 g, 6.64 mmol) in anhydrous dichloromethane (4 ml_). The resulting warm mixture (from slight exotherm) was stirred at ambient temperature for 30 min and quenched with the addition of cold water (20 ml_). Solid sodium carbonate was added until a pH of 10 was reached, and the mixture was stirred at ambient temperature for 1 hour. The organic layer was separated and the aqueous layer back-extracted withdichloromethane (4 x 30 ml_). The combined organic layers were passed through a phase separator column and concentrated under reduced pressured to yield crude ethyl 3-(1 ,2-benzoxazol-3-ylamino)-3- oxopropanoate.
According to the analysis of related databases, 36216-80-5, the application of this compound in the production field has become more and more popular.
