Adding a certain compound to certain chemical reactions, such as: 4139-61-1, 6-Bromo-4-hydroxycoumarin, 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, COA of Formula: C9H5BrO3, blongs to alcohols-buliding-blocks compound. COA of Formula: C9H5BrO3
EXAMPLE 27 6-Bromo-4-hydroxy-3-[4-(2-methoxyphenyl)butyl]-2H-1-benzopyran-2-one The title compound was prepared from 4-hydroxy-6-bromo-2H-1-benzopyran-2-one, and 4-(2-methoxyphenyl)butanoic acid using the procedure described in Example 13. A 55% yield of the title compound was obtained, m.p. 147.5-148.5 C.
The synthetic route of 4139-61-1 has been constantly updated, and we look forward to future research findings.
