36216-80-5, Rate laws may be derived directly from the chemical equations for elementary reactions. This is not the case, however, for ordinary chemical reactions.Benzo[d]isoxazol-3-amine, cas is 36216-80-5,the Benzisoxazole compound, below Introduce a new synthetic route.
Example 77; (3R)-1-[2-(1,2-Benzisoxazol-3-ylamino)-2-oxoethyl]-3-{[2-piperidin-1-yl-2-(2-thienyl)propanoyl]oxy}-1-azoniabicyclo[2.2.2]octane chloride (Isomer 1); a) N-1,2-Benzisoxazol-3-yl-2-chloroacetamide; Benzo[d]isoxazol-3-amine (1 g) and cesium carbonate (2.429 g) in dry DMF (20 mL) was stirred at 23 C. whilst bromoacetyl chloride (0.624 mL) was added dropwise to the mixture. After stirring for 8 h, the reaction was poured into water (100 mL) and the mixture extracted with diethyl ether (2¡Á200 mL). The combined extracts were dried over magnesium sulfate and concentrated to dryness. The crude product was purified on silica gel using 40% ether isohexane. The subtitled compound was isolated as a colourless solid (0.5 g).m/e 210 [M+H]+ 1H NMR (400 MHz, DMSO) delta 11.45 (1H, s), 8.02 (1H, d), 7.72-7.63 (2H, m), 7.39 (1H, ddd), 4.47 (2H, s).
According to the analysis of related databases, Benzo[d]isoxazol-3-amine, the application of this compound in the production field has become more and more popular.
