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 7699-18-5 as follows. Computed Properties of C9H9NO2
General procedure: Compounds 8 and 10 were prepared from azo coupling of aryldiazonium salts 3a,b with5-methoxyindolin-2-one 2, previously described [24]. Aryldiazonium salts were prepared startingto corresponding amines (21.5 mmol) in HCl 6N (11 mL) with water solution (7.5 mL) of sodiumnitrite (23 mmol). This solution was added to solution of indol-2-one (21.5 mmol) and sodium acetate(43 mmol) in methanol (59 mL) at 0 C. The resulting precipitate was filtered and purified.
According to the analysis of related databases, 7699-18-5, the application of this compound in the production field has become more and more popular.
