Synthetic Route of 313339-92-3, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 313339-92-3 as follows.
A solution of 3,5-dichloropyrazine-2-carbonitrile (150 mg, 0.862 mmol), (R)-2-amino-2-phenylacetamide hydrochloride (160 mg, 0.858 mmol) and DIEA (0.400 mL, 2.30 mmol) in DMF (5 mL) was stirred at room temperature for 6 h. Water and EtOAc were added. Organic phase was separated, washed with 1N HCl, then with 5% NaHCO3, dried over Na2SO4, concentrated in vacuo to give (R)-2-(6-chloro-5-cyanopyrazin-2-ylamino)-2-phenylacetamide (245 mg).
According to the analysis of related databases, 313339-92-3, the application of this compound in the production field has become more and more popular.
