1663-61-2, name is (Triethoxymethyl)benzene, belongs to ethers-buliding-blocks compound, is considered to be a conventional heterocyclic compound, which is widely used in drug synthesis. The chemical synthesis route is as follows. Product Details of 1663-61-2
EXAMPLE IV 1-acetyl-5-butyryl-3-(ethoxy-phenyl-methylidene)-2-indolinone 10 g (49 mmol) 5-butyryl-2-indolinone (Ex. 1.2) are stirred in 200 ml acetic anhydride for 5 h at 130¡ã C. Then 35 ml triethyl orthobenzoate are added and the mixture is stirred for a further 4 h at 100¡ã C. Then it is evaporated down and the resulting precipitate is suction filtered, washed and dried. Yield: 11.5 g (62percent of theory) Rf=0.79 (silica gel, ethyl acetate/cyclohexane/methanol 9:9:2) C23H23NO4 (MW=377.438) Mass spectrum: m/z=378 (M+H)+
The synthetic route of 1663-61-2 has been constantly updated, and we look forward to future research findings.
