permanganate gave 1-(4-methylsulfonylphenyl)-5-aryl-1,2,3-triazoles 5. Similarly, condensation of 4-(N,N-dibenzylaminosulfonyl)aniline with aryl aldehyde followed by 1,3-cycloaddition of diazomethane with the imino compound 11 and the subsequent oxidation of triazoline 12 with potassium permanganate yielded the triazole 13. Debenzylation of compound 13 with sulfuric acid gave the desired compound 1-(4-amino
4-甲基磺酰基苯胺与芳基醛在乙醇-四氢呋喃中的缩合得到亚氨基化合物3。将重氮甲烷与化合物3进行1,3环加成,然后将三唑啉4用高锰酸钾氧化,得到1-(4-甲基磺酰基苯基)-5-芳基-1,2,3-三唑5。类似地,将4-(N,N-二苄基氨基磺酰基)苯胺与芳基醛缩合,然后将重氮甲烷与亚氨基化合物11进行1,3-环加成,然后将三唑啉12与高锰酸钾氧化,制得三唑13。化合物13的脱苄基作用用硫酸得到所需的化合物1-(4-氨基磺酰基苯基)5-芳基-1,2,3-三唑14。
