Adding a certain compound to certain chemical reactions, such as: 1663-61-2, name is (Triethoxymethyl)benzene, belongs to ethers-buliding-blocks compound, 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 1663-61-2, Application In Synthesis of (Triethoxymethyl)benzene
EXAMPLE III 1,5-diacetyl-3-(ethoxy-phenyl-methylidene)-2-indolinone 32.6 g (150 mmol) 1,5-diacetyl-2-indolinone are suspended in 100 ml triethyl orthobenzoate and stirred overnight with 150 ml acetic anhydride at 110° C. Then a further 50 ml triethyl orthobenzoate are added and the mixture is stirred for a further 24 h. Then it is evaporated down and the resulting precipitate is suction filtered, washed and dried. Yield: 38 g (72.5percent of theory) Rf=0.60 (silica gel, methylene chloride/methanol 30:1) C21H19NO4 (MW=349.384) Mass spectrum: m/z=350 (M+H)+
At the same time, in my other blogs, there are other synthetic methods of this type of compound, (Triethoxymethyl)benzene, and friends who are interested can also refer to it.
