Adding a certain compound to certain chemical reactions, such as: 132898-96-5, name is 2,3-Dioxoindoline-5-sulfonyl chloride, belongs to indolines-derivatives compound, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 132898-96-5, Recommanded Product: 132898-96-5
To a mixture of 2,3-dioxoindoline-5-sulfonyl chloride (0.800 g, 3.26 mmol) in dry THF (10 ml), cooled at 0 C. under nitrogen, DIPEA (1.138 ml, 6.51 mmol) and dimethylamine 2M in THF (2.117 ml, 4.23 mmol) were added, and the mixture was allowed to stir at room temperature for 2.5 hours. The mixture was partitioned between ethyl acetate and water, and the aqueous layer was extracted three times with ethyl acetate. The combined organic layers were dried over sodium sulfate and evaporated to dryness to give N,N-dimethyl-2,3-dioxoindoline-5-sulfonamide (0.639 g, 2.51 mmol, 77% yield). MS/ESI+ 254.9 [MH]+.
