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. 107017-73-2, name is tert-Butyl (1-(hydroxymethyl)cyclopropyl)carbamate, A new synthetic method of this compound is introduced below., category: amides-buliding-blocks
A solution of potassium tert-butoxide (1? 5eq) was added to a solution of (1-hydroxymethylcyclopropyl) -tert-butoxycarbonylamino in tetrahydrofuran [THF] at room temperature. After stirring for 30 min, 4-fluoro-2-isopropyl Oxy-1-nitrobenzene (1.3 eq) and heated to 50 C overnight. After completion of the reaction, the reaction solution was cooled, poured into water and extracted three times with ethyl acetate. The organic phase was washed with saturated brine, dried over anhydrous sodium sulfate and then poured onto the column. PE [petroleum ether]: EA [ethyl acetate] Volume ratio) = 5: 1 to obtain compound 4-3.
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.
