As a common heterocyclic compound, it belongs to isothiazole compound, name is 4-Bromoisothiazole, and cas is 24340-77-0, its synthesis route is as follows.,24340-77-0
Intermediate 58: Methyl 6-(benzenesulphonylmethyl)-3-(isothiazol-4-yl)-2-methoxybenzoate[0588] A mixture of methyl 6-(benzenesulphonylmethyl)-2-methoxy-3-(4,4,5,5- tetramethyl-l,3,2-dioxaborolan-2-yl)benzoate (Intermediate 59, 0.15g), tri-tert-butyl- phosphinium tetrafluoroborate (O.Olg), cesium carbonate (0.34g), tris-(dibenzylideneacetone)- dipalladium (0.016g), and 4-bromoisothiazole (0.06g) in dioxane (3.2ml) and water (0.4ml) was degassed and then heated in the microwave at 120C for 20 minutes. After cooling, the mixture was diluted with ether, dried (MgS04) and filtered. The filtrate was evaporated to dryness and the residue was purified by chromatography on silica, eluting with a mixture of ethyl acetate and cyclohexane with a gradient of 0-60% to give crude methyl 6- (benzenesulphonylmethyl)-3-(isothiazol-4-yl)-2-methoxy-benzoate (0..044g) as an oil. The material was used without further purification or characterisation.
With the complex challenges of chemical substances, we look forward to future research findings about 24340-77-0,belong isothiazole compound
