Synthetic Route of 26021-57-8, Adding some certain compound to certain chemical reactions, such as: 26021-57-8, name is 3,4-Dihydro-2H-benzo[b][1,4]oxazin-6-ol,molecular formula is C8H9NO2, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound 26021-57-8.
1-(6-hydroxy-2,3-dihydro-4H-benzo[b][1,4]oxazin-4-yl)ethan-1 -one (72). Compound 54 (1 g, 6.62 mmol) was suspended in 10 mL Dl water, to which Acetic anhydride (2.5 mL, 26.46 mmol) was added dropwise. The reaction mixture was placed in an ultrasonication bath for 1 min, then was stirred in a water bath (50 C) for 10 min. The resulting solution was stirred overnight at rt. After which, the solid was collected via vacuum filtration and washed with small portions of Dl water. The product was left in the funnel and air dried overnight to afford compound 72 (1.21 g, 95%) as a white solid, which was used for the next step without further purification.
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. 26021-57-8, 3,4-Dihydro-2H-benzo[b][1,4]oxazin-6-ol, other downstream synthetic routes, hurry up and to see.
