239097-74-6, In the next few decades, the world population will flourish. As the population grows rapidly and people all over the world use more and more resources, all industries must consider their environmental impact.239097-74-6,Benzo[d]isoxazol-5-amine, it is a common compound, a new synthetic route is introduced below.
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.
