The treatment of alkylated nitro derivatives of indazole with stannous chloride in alkanethiol gave after coupling of the obtained amines with 4-methoxybenzenesulfonyl chloride in pyridine the new N-(4-Alkylsulfanylindazol-7-yl)-4-methoxybenzene sulfonamides via the nucleophilic substitution of hydrogen in position 4 of indazole, together with the expected 4-methoxy-N-(indazol-7-yl)-benzenesulfonamides. All the newly synthesized compounds have been characterized by elemental analysis and spectroscopic data.
- N-(4-Alkyl sulfanylindazol-7-yl)arylsulfonamide
- stannous chloride
