N-(p-Methoxyphenyl)glycine ethyl ester and N-(p-ethoxyphenyl)glycine ethyl ester were each reacted with benzenesulfonyl or p-toluenesulfonyl chloride in pyridine to form N-(p-alkoxyphenyl)-N-(arylsulfonyl)glycine ethyl esters (II) and these were reacted with hydrazine to form N-(p-alkoxyphenyl)-N-(arylsulfonyl)glycine hydrazine (III). Application of arylsulfonyl chloride to (III) or N-(p-alkoxyphenyl)glycine hydrazide (V) in pyridine affords 1-[N-(p-alkoxyphenyl)-N-(arylsulfonyl)glycyl]-2-(arylsulfonyl)hydrazine (IV). Reaction of (V) and arylsulfonyl chloride in dehyd. ethanol affords (IV) and 1-[N-(p-alkoxyphenyl)glycyl]-2-(arylsulfonyl)hydrazine (VI). Further application of arylsulfonyl chloride to (VI) in pyridine affords (IV).
