4570-41-6,With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.4570-41-6,Benzo[d]oxazol-2-amine,as a common compound, the synthetic route is as follows.
To a colorless solution ofbenzo[d]oxazol-2-amine(200 mg, 1.491 mmol) in DMF (10 ml) was added sodiumhydroxide (20N, 149 mul., 2.98 mmol), to give a green suspension.The mixture was stirred for 15 min at room temperature.Carbon disulfide (225 ul., 3.73 mmol) was added to give adark brown solution. The reaction was stirred for 15 min atroom temperature, followed by the addition of sodiumhydroxide (20N, 149 ul., 2.98 mmol) and stirred for an additional 10 min. Iodomethane (224 mul., 3.58 mmol) was then added dropwise. A green solid precipitated after 12 min. Thereaction stirred for a further 2 hr. The solid was collected byfiltration, washed with DMF (2xl ml), H20 (2xl ml), driedunder the house vacuum for 30 min and further dried in anoven in vacuo over night to afford the expected product,dimethyl benzold]oxazol-2-ylcarbonimidodithioate (258.5mg, 1.085 mmol, 72.7percent yield), as a white solid
As the paragraph descriping shows that 4570-41-6 is playing an increasingly important role.
