Some tips on 288-16-4

With the complex challenges of chemical substances, we look forward to future research findings about 288-16-4,belong isothiazole compound

As a common heterocyclic compound, it belongs to isothiazole compound, name is Isothiazole, and cas is 288-16-4, its synthesis route is as follows.,288-16-4

To a solution of isothiazole (5 g, 0.06 mol) in anhydrous THF (50 mL) was added n- BuLi (28.2 mL, 0.07 mol) dropwise at -70 oC over 1 h. After stirring at -70 oC for 1 h, Br2 (6 mL, 0.12 mol) was added dropwise over 30 min and the resulting mixture was allowed to warm to RT and poured into an excess of cold 2N HCl solution. The organic layer was separated and the aqueous layer was extracted with Et2O (200 mL x 3). The combined organic extracts were washed with saturated sodium dithionite solution (200 mL x 2), dried over anhydrous Na2SO4, and filtered. The filtrate was concentrated in vacuo, and the resulting residue was distilled to afford 5-bromoisothiazole (2 g, 21%) as yellow oil.1H NMR (400 MHz, CDCl3) delta 8.33 (d, J = 1.6 Hz, 1H), 7.28 (d, J = 1.6 Hz, 1H).

With the complex challenges of chemical substances, we look forward to future research findings about 288-16-4,belong isothiazole compound
