Electric Literature of 35179-98-7, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 35179-98-7, name is Chloromethyl ethyl carbonate, This compound has unique chemical properties. The synthetic route is as follows.
To DMF (10 mL) were added chloromethyl ethyl carbonate (0.66 g, 4.77 mmol),potassium carbonate (1.00 g, 7.16 mmol) and (2S,3S)-3-((2-bromo-6-(5-chlorothiophen-2-yl)-5-fluoropyrimidin-4-yl)amino)bicyclo[2.2.2]octane-2-carboxylic acid (1.10 g, 2.39 mmol) andthe mixture was stirred at rt overnight. To the reaction mixture was added water (40 mL), and theresulting mixture was extracted with ethyl acetate (30 mL x 3). The combined organic layerswere washed with saturated brine (30 mL), dried over anhydrous sodium sulfate and filtered. Thefiltrate was concentrated and the residue was purified by silica gel column chromatography(PE/EtOAc (v/v) = 1511) to give the title compound as a light yellow solid (0.90 g, 67 %).
The chemical industry reduces the impact on the environment during synthesis Chloromethyl ethyl carbonate. I believe this compound will play a more active role in future production and life.
