As a common heterocyclic compound, it belongs to isothiazole compound, name is 2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide, and cas is 936-16-3, its synthesis route is as follows.
2,3-dihydro-1,1-dioxo-1,2-benzoisothiazole (150 mg, 0.887 mmol), N-Boc-bromoethylamine (238mg, 1.064mmol) And cesium carbonate (867mg, 2.66mmol) in 5ml DMF, It was then stirred overnight. On the following day, after the reaction was detected by TLC, water was added for extraction. It was washed with saturated brine and dried over anhydrous sodium sulfate. Suction filtration, the filtrate was concentrated under reduced pressure, the crude product was separated by column chromatography, 124 mg of a white solid were obtained with a yield of 45%.
936-16-3, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,936-16-3 ,2,3-Dihydrobenzo[d]isothiazole 1,1-dioxide, other downstream synthetic routes, hurry up and to see
