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.,936-16-3
Step 2. A mixture of 14 (200 mg, 0.70 mmol), 1 (143 mg, 0.84 mmol), Cs2CO3 (459 mg, 1.41 mmol), Cul (40 mg, 0.21 mmol) and 2-(dimethylamino)acetic acid hydrochloride (30 mg, 0.21 mmol) in dioxane (2 mL) was degassed and purged with N2 (3X). The mixture was stirred at 100¡ãC for 12 h under N2 atmosphere. The reaction mixture was diluted with ethyl acetate (50 mL), adjusted to pH=7 with 2N HC1, and separated. The aqueous layer was extracted with ethyl acetate (2 x 40 mL) and the combined organic layer was washed with saturated brine (80 mL), dried over anhydrous sodium sulfate, filtered and concentrated to give 15 (230 mg) as a light yellow solid.
With the complex challenges of chemical substances, we look forward to future research findings about 936-16-3,belong isothiazole compound
