| titleOfInvention | The preparation method of -4 picoline of medicine intermediate 2,6- di-t-butyl |
| abstract | The invention discloses medicine intermediate 2, the preparation method of -4 picoline of 6- di-t-butyl specifically includes following steps：First using trimethyl-aceyl chloride, the tert-butyl alcohol, trifluoromethanesulfonic acid as raw material preparation 2,6- di-t-butyl -4 furans drone salt is used span80 to be surface modified first then using alumina silicate powder as raw material, then maleic anhydride is added dropwise to be modified, last and PVP solution mixing system obtains spinning solution, so that PVP/ alumina silicate composite fibre is prepared, then using it as catalyst, with obtained above 2,6- di-t-butyl -4 furans drone salt is raw material, is reacted in concentrated ammonia liquor, and target product is made.This method reaction efficiency disclosed by the invention is big, and product yield is high. |
