36216-80-5, Benzo[d]isoxazol-3-amine is a Benzisoxazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
Benzisoxazole-3-amine 2 (2.68 g, 20 mmol) was dissolved in water (25 ml) and concentrated HCl (12.5 ml) under vigorous stirring in an ice/water bath. A freshly prepared, ice-cold solution of NaNO2 (1.4 g, 20 mmol) in water (10 ml) was added drop wise to the reaction mixture by keeping the internal temperature between 0 to 5 C. After the completion of addition, the reaction mixture was stirred for an additional 10 min. A freshly prepared solution of sodium azide (1.3 g, 20 mmol) in water (10 ml) was added drop wise to the reaction mixture via an additional funnel while keeping the internal temperature of the reaction mixture below 5 C. Upon complete addition of the sodium azide solution, the reaction mixture was stirred for an additional 20-30 min at 0 C, followed by stirring at room temperature for another 3 h. The reaction mixture was extracted with ethyl acetate EtOAc (25 ml) three times. The combined organic layer was washed with water (25 ml) and brine (25 ml), dried over anhydrous sodium sulphate and concentrated under reduced pressure to get crude benzisoxazole-3-azide 3, which was purified by column chromatography over silica gel (60-120 mesh) using hexane/EtOAc (8:2) as eluent. The pure benzisoxazole-3-azide 3 was stored at 2-5 C in the refrigerator.
As the paragraph descriping shows that 36216-80-5 is playing an increasingly important role.
