Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 5466-88-6, name is 2H-1,4-Benzoxazin-3(4H)-one, A new synthetic method of this compound is introduced below., SDS of cas: 5466-88-6
General procedure: Phosphoric acid (3.15 g, 0.032 mol) and TFAA (21.8 mL, 0.104 mol) were added to the mixture of 4H-Benzo [1,4]oxazin-3-one (4 g, 0.026 mol) and substituted phenylacetic acid (1.1eq), at 0 C. After completion of addition, the mixture was allowed to warm to room temperature and stirred for 1 h. The reaction mixture was cooled to 0 C and adjusted the pH to 7 by adding the saturated NaHCO3 solution. The precipitated solid was filtered, washed with water and dried to give the desired product.
The basis of chemical reaction formula synthesis, the synthesis route is composed of some specific reactions and combined according to certain logical thinking. We look forward to the emergence of more reaction modes in the future.
