Methods The amides were prepared from tryptophan and different acid t1erivaties by the catalytic dehydration of dicyclohexyl carbodiimide. The characteristic heterocyclic ring system of 5-(3'-indolyl)-oxazoles was constructed by oxidative cyclization of amide, using dicholorodicyanoquinone.

以色氨酸为原料，与取代的苯甲酸在DCC催化下脱水缩合得到酰胺，再通过DDQ芐位氧化和分子内环合件成5-（3'-吲哚基）-恶唑。

Methods Activate groups A and C meningococcal polysaccharide with cyanogens bromide and prepare into MenAPS-ADH and MenCPS-ADH derivatives by reacting with 1, 6-adipic acid dihydrazine. Mix MenAPS-ADH and MenCPS-ADH derivatives with purified tetanus toxoid at a certain mass ratio, then add l-ethyl-3(3-dimethylaminopropyl)-carbodiimide to prepare bulks of MenAPS-TT and MenCPS-TT conjugates respectively. Mix the two bulks at a certain ratio, add stabilizer and lyophilize to prepare group A+C meningococcal polysaccharide conjugate vaccine.
