3,5-Di-tert-butyl-2-hydroxybenzaldehyde - Reference Information

introduction	3, 5-di-tert-butylsalicylaldehyde is an organic intermediate, which can be prepared from 2, 4-di-tert-butylphenol through one-step reaction. It has been reported that it can be used to prepare dimethyl ethylenediamine tert-butylphenol and (S,S)-salenCo (II) catalyst.
apply	500mL eggplant bottle to add 2,4-di-tert-butylphenol 50mmol, paraformaldehyde 500mmol, sodium hydroxide 150mmol, triethylamine 100mmol, tetrahydrofuran 100mL, heating reflux stirring reaction at 90 ℃, TLC tracking the reaction process, after the reaction to room temperature. Add hydrochloric acid to the reaction solution, stir, until the reaction solution is clarified and stratified, the aqueous phase is extracted with ethyl acetate, the organic phase is combined, and the saturated salt water is washed, anhydrous sodium sulfate is dried, filtered, and the solvent is removed. Column chromatography (n-hexane: ethyl acetate = 30:1) purification, the product is 10.56g, and the yield is 90.16%.
