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. 141452-01-9, name is Methyl indoline-5-carboxylate, A new synthetic method of this compound is introduced below., HPLC of Formula: C10H11NO2
The indoline-5-carboxylate (177mg, 1.0mmol) was dissolved in pyridine (4mL), and4- (4- (2- (3- (chlorosulfonyl) benzamido) -4,5,6,7-tetrahydro-benzo [b] thiophen-3-carboxamido) phenethyl) benzoate (800mg, 1.26mmol),The reaction was heated to reflux for 18 hours.The reaction solution was diluted with ethyl acetate (80mL),0.1mol / L hydrochloric acid and washed (10mL ¡Á 3).The organic phase was dried over anhydrous sodium sulfate,concentrate.The crude product was purified by silica gel column chromatography (petroleum ether / dichloromethane (v / v) = 1/1) to give a yellow solid 491mg,Yield: 63.2%.
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.
