239097-74-6, 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-5-amine, cas is 239097-74-6,the Benzisoxazole compound, below Introduce a new synthetic route.
To a suspension of the ester compound from the procedure above (105 mg, 0.340 mmol) in DMF (0.5 mL) was added a solution of l,2-benoxazol-5-amine (46 mg, 0.340 mmol) in DMF (0.5 mL). The reaction mixture was stirred at room temperature for 2 hours until the reaction was complete, and quenched with the addition of TFA (5 drops). The precipitated solid was collected by filtration, suspended in DCM, basified with saturated aHC03to pH ~8. The aqueous layer was extracted with DCM, dried over anhydrous a2S04, filtered andconcentrated to provide a residue. The residue was purified by prep-HPLC (MeCN/H20) to provide the title compound (40 mg, 38%) as a white solid.XH NMR (400 MHz, CDC13) delta 10.31 (s, 1H), 8.72-8.71 (m, 2H), 8.45 (d, J= 1.6 Hz, 1H), 7.67 (dd, J= 9.2 Hz, 2.0 Hz, 1H), 7.60 (d, J= 9.2 Hz, 1H), 6.79 (s, 1H), 2.84 (s, 3H), 2.74 (s, 3H). ES-MS m/z: 308.0 [M+H]+. HPLC Purity (214 nm): 98%; tR= 9.36 min.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles. 239097-74-6, other downstream synthetic routes, hurry up and to see.
