Analyzing the synthesis route of 5908-62-3

5908-62-3 1,1-Dioxo-isothiazolidine 642157, athiazolidine compound, is more and more widely used in various fields.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.5908-62-3,1,1-Dioxo-isothiazolidine,as a common compound, the synthetic route is as follows.,5908-62-3

To a solution of tert-butyl (3S)-3- [[4- [2- [(5 -iodo-2-methyl- 1 -naphthyl)oxy]-3 – pyridyl]pyrimidin-2-yl]amino]piperidine-1-carboxylate (110 mg, 0.17 mmol) in CH3CN (2 mL) was added 1,3-propanesultam (209.1 mg, 1.73 mmol), copper iodide (1.6 mg, 0.01 mmol), N,N?-dimethyl-1,2-ethanediamine (7.6 mg, 0.09 mmol) and potassium carbonate (47.8 mg, 0.34 mmol). The mixture was purged with N2 and stirred at 80 C for 88 h. After cooling down, the mixture was filtered, concentrated, dissolved in ethyl acetate (60 mL) and washed with H20 (50 mL x 2). The organic phase was dried over anhydrous sodium sulfate and concentrated and the residue was purified by Prep-TLC (50% ethyl acetate in petroleum ether,Rf= 0.1) to yield 55 mg (51%) of the title compound as a brown oil. LCMS (ESI) [M+H]=631.0.
