Abstract
Reaction of (4-pyridylmethyl)amine (3) with benzenesulfonyl chlorides 2a—i affords the corresponding N-(4-pyridylmethyl)benzenesulfonamides 4a—i which are converted into the N-oxides 5 by treatment with hydrogen peroxide and acetic acid. Treatment of compounds 4 with their N-oxides 5 in acetic anhydride results in dimerization to give the corresponding N,N′-bis(phenylsulfonyl)-1,2-bis(4-pyridyl)ethylenediamines 6a–d, f. The mixed ethylenediamines 6e, g are similarly synthesized from differently substituted sulfonamides and N-oxides.
