Downstream synthetic route of Benzo[d]isoxazol-3-amine

Chemical properties determine the actual use. Each compound has specific chemical properties and uses. We look forward to more synthetic routes in the future to expand reaction routes of Benzo[d]isoxazol-3-amine, 36216-80-5

36216-80-5, 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. Benzo[d]isoxazol-3-amine, cas is 36216-80-5,the Benzisoxazole compound, it is a common compound, a new synthetic route is introduced below.

To a stirred solution of 1-(3-phenyl-1,2,4-thiadiazol-5-yl)piperidine- 4-carboxylic acid (289 mg, 1.00 mmol) and DMF (0.010 mL) in THF (5.0 mL) was added oxalyl chloride (0.174 mL, 2.00 mmol) dropwise at 0 C. After stirring at room temperature for 1 h, the solvent was concentrated in vacuo. To the residue were added THF (5.0 mL), benzo[d]isoxazol-3-amine (134 mg, 1.00 mmol), and pyridine (0.404 mL, 5.00 mmol) at 0 C. The mixture was stirred at room temperature for 1.0 h, and the solvent was concentrated in vacuo. The residue was purified by silica gel column chromatography (hexane-EtOAc), and recrystallized from EtOAc- hexane to give 65a (60.3 mg, 15%) as colorless crystals, mp 204- 205 C. 1H NMR (300 MHz, CDCl3) d: 2.05-2.22 (4H, m), 2.88 (1H, bs), 3.36-3.45 (2H, m), 4.11-4.18 (2H, m), 7.32-7.63 (6H, m), 8.19-8.27 (3H, m), 9.46 (1H, br s). Analytical HPLC showed 97.4% purity.
