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. 7699-18-5, name is 5-Methoxyindolin-2-one, This compound has unique chemical properties. The synthetic route is as follows., Computed Properties of C9H9NO2
General procedure: Amixture of 2-oxindole (5.19 mmol), 4-(dimethylamino)cinnamaldehyde (5.71mmol) and piperidine (3.11 mmol) in methanol (20 mL) was heated under refluxfor 18 h. Then, the mixture was concentrated under reduced pressure. The residuewas purified by silica gel column chromatography (hexane/ethyl acetate/methanol= 50/50/1) to afford A (Y1 =H, 55%) as reddish brown crystals.
Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of 7699-18-5.
