Reaction of methyl acrylate with 4-chlorobenzenethiol gave methyl 3-[(4-chlorophenyl)thio]propanoate 1. The latter on oxidation with hydrogen peroxide gave methyl-3-[(4-chlorophenyl)sulfonyl]propanoate 2. 3-[(4- chlorophenyl)sulfonyl] propane hydrazide 3 was prepared from methyl-3-[(4-chlorophenyl)sulfonyl] propanoate 2 by reaction with hydrazine hydrate. A new series of derivatives were synthesised from 3-[(4-chlorophenyl)sulfonyl] propane hydrazide 3. The structural elucidation of these compounds was based on their IR, 1H NMR and Mass spectral data.
