Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 35179-98-7, name is Chloromethyl ethyl carbonate, A new synthetic method of this compound is introduced below., category: esters-buliding-blocks
J. (R)-3-[N-(5′-Chloro-2′-fluorobiphenyl-4-methyl)-N’-oxalylhydrazino]-2-hydroxy-propionic Acid Ethoxycarbonyloxymethyl Ester A mixture of (R)-3-[N’-t-butoxyoxalyl-N-(5′-chloro-2′-fluorobiphenyl-4-ylmethyl)hydrazino]-2-hydroxypropionic acid (270 mg, 580 mumol), chloromethyl ethyl carbonate (160 mg, 1.16 mmol), NaI (174 mg, 1.2 mmol) and 2,6-dimethylpyridine (620 mg, 5.8 mmol) in DMF (10 mL) was stirred at room temperature overnight. The mixture was poured into water (30 mL) and the mixture was then extracted with EtOAc (3*30 mL). The combined organic layers were washed with saturated aqueous NaCl (2*30 mL), dried over anhydrous Na2SO4, and concentrated in vacuo. The crude Compound 1 (300 mg) was used without purification. LC-MS: 569 [M+H]+.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
