One of the major reasons is to use measurements of the macroscopic properties of a system, such as the rate of change in the concentration of reactants or products with time, to discover the sequence of events that occur at the molecular level.Benzo[d]isoxazol-3-amine, cas is 36216-80-5,the Benzisoxazole compound, introduce a new downstream synthesis route. 36216-80-5
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).
In every case, we must determine the overall rate law from experimental data and deduce the mechanism from the rate law (and sometimes from other data). you can also browse my other articles about 36216-80-5, if you are interested., 36216-80-5
