With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.7716-66-7,3-Chlorobenzo[d]isothiazole,as a common compound, the synthetic route is as follows.
7716-66-7, To a solution of 3-chlorobenzo[d]isothiazole (0.5 00 g, 2.941 mmol) in sulphuric acid (5 mL) was added potassium nitrate (272 mg, 2.69 mmol) portion wise at 0-5¡ãC. The reaction mass was stirred at rt for 12 h. The reaction mass was quenched with water and the precipitate obtained was filtered. The precipitate was purified by column chromatography to afford 220 mg of the title product. 1H NMR (300 MHz, CDC13): delta 8.59 (d, J = 7.8 Hz, 1H), 8.40 (d, J = 7.8 Hz, 1H), 7.76 (t, / = 7.8 Hz, 1H).
7716-66-7 3-Chlorobenzo[d]isothiazole 598190, aisothiazole compound, is more and more widely used in various.
