Synthetic Route of 58656-98-7, 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 58656-98-7 as follows.
A Preparation of (26) where R10 is 2-Cyanoindole A mixture of 3.0 g (0.02 mol) of 2-cyanoindole, 4.2 g (0.02 mol) of tert-butyl-4-fluorobenzoate, and 5.5 g (0.04 mol) of potassium carbonate in 30 ml dimethyl sulfoxide was heated at 110 C. for 48 hours. The reaction was poured onto ice-water and extracted twice with ethyl acetate. The organic extracts were combined, washed with water and dried over magnesium sulfate. Evaporation yielded a dark oil which was flash chromatographed on silica gel, eluding with ethyl acetate-hexane 1:9 to give 3.6 g (0.011 mol) of 1-[4-(tertbutoxycarbonyl)phenyl]-2-cyanoindole as an oil.
According to the analysis of related databases, 58656-98-7, the application of this compound in the production field has become more and more popular.
