RARECHEM AL BF 0483 - Reference Information
| application | methylbenzothiophene-2-formaldehyde is an organic synthesis intermediate, which can be used in laboratory research and development processes and chemical and pharmaceutical synthesis, and can be obtained by esterification of benzothiophene-2-formic acid. It can be used to synthesize 2-substituted -1,3, 4-oxadiazinone compounds-compound 4. |
| preparation | 14.25g (80 mmol) indole -2-formic acid is dissolved in 500 mL methanol, 2 mL concentrated sulfuric acid is added, reflux reaction is carried out at 75 ℃ for 24 h, TLC (5% water-acetonitrile) monitors the reaction process. after the reaction is completed, most of the solvent is evaporated under reduced pressure, the solution was cooled and let stand at 0 ℃ for about 10 h, needle crystals were precipitated, and 15.36g of methyl benzothiophene-2-formate (1) was obtained by filtration with a yield of 93%. |
