36216-80-5, We know that the rate of many reactions can be accelerated by catalysts. A catalyst speeds up the rate of a reaction by lowering the activation energy; in addition, the catalyst is regenerated in the process. Benzo[d]isoxazol-3-amine, cas is 36216-80-5,the Benzisoxazole compound, below Introduce a new synthetic route.
a) N-Benzo[d]isoxazol-3-yl-2-chloro-acetamide To a mixture of benzo[d]isoxazol-3-ylamine (1 g) and cesium carbonate (2.42 g) in dry DMF (20 mL), stirred at rt, was added bromoacetyl chloride (0.62 mL) by dropwise addition. After stirring the mixture for 8 hours, the reaction was poured into water (100 mL) and the products extracted into ether (2*200 mL). The combined extracts were dried over magnesium sulfate and concentrated to dryness. The crude product was purified on silica gel using ether/isohexane (4/6) to afford the sub-titled compound as a colourless solid (0.5 g). m/e 210 [M+H]+
This compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,Benzo[d]isoxazol-3-amine,36216-80-5,its application will become more common.
